Question

8x+2y=10
Please help me solve this step by step
WILL MEDAL AND FAN

Answer 1

try changing a variable with 0

Answer 2

So unless you are solving for a viable, you can not solve this. Are you perchance asked to solve for y?

Answer 3

yes, solve the equation for Y

Answer 4

ok, so can you tell me the order of operations?

Answer 5

pemdas

Answer 6

ok so when we are solving for a variable, we are essentially reversing the order of operations. So we do SadMep So first, is there anything being added or subtracted from our y term?

Answer 7

8x

Answer 8

right, and are we adding or subtracting?

Answer 9

adding

Answer 10

right, So how do we "undo" addition?

Answer 11

by subtracting

Answer 12

good, now, what will we need to subtract FROM BOTH SIDES in order to make no addition on our y term?

Answer 13

then, please do that subtraction

Answer 14

8x?

Answer 15

8x+2y=10
-8x
2y=10-8x
divide by 2
y=5-4x
rewrite
y=-4x+5

Answer 16

yea, so make sure you subtract that from both sides

Answer 17

@susie.gg98 please do not just give answers. We are here to help

Answer 18

@Love_k what did you get from your subtraction?

Answer 19

@FibonacciChick666 She asked for step-by-step help and thats what I did, I did not just simply "give" an answer, I showed how to get to the answer, therefore I am helping. Please do not say things that don't make sense

Answer 20

What you did provides no assistance in attaining an understanding Any student could simply copy and claim it as their work, hence, just an answer.

Answer 21

keep calm guys

Answer 22

You also did not make a point that you were doing these things to both sides which can cause a fundamental misunderstanding. Please if you are just going to give a full answer, at least explain the concept in full instead of taking shortcuts in notation.

Answer 23

My apologies @Love_k , did you still need to continue the process?

Answer 24

It provides assistance by showing a student exactly how its done. I don't know about you but for me, when learning a math problem , the way you explain it does not help me whatsoever. I have to visually see the steps to get help and many others are like that. A student can copy what you are saying too making your help just an answer as well. Teachers at school give examples just like what I provided, and that doesn't mean they just simply "gave me an answer." Also I did show that I did it to both sides when I provided the statement after. Please don't be so irrelevant

Answer 25

I think i know how to do it i just forgot the process of it and needed an example thank you guys!

Answer 26

No problem :) I knew an example would help you

Answer 27

If that were the case you would have shown a different problem, for example*. Please stop trying to pass just doing the problem and giving an answer as an example.

Example *
\[3x+6y=12\]First thing we need to do is get the y-term by itself. So we will subtract 3x from both sides. \[3x-3x+6y=12-3x\] Then we simplify to obtain
\[6y=12-3x\]
Now we need to remove the multiplication of 6 on our y-term. To do this we multiply both sides by \(\frac{1}{6}\). We then have: \[(\frac{1}{6})6y=\frac{1}{6}(12-3x)\]
Using the distributive property and multiplying the left side out, we obtain:
\[y=2-0.5x\]


^Above is an example problem with explanation. In future please remember to explain your work and potentially create a new question if it is just to be an "example"

Answer 28

Hope the method makes sense, always try to think it out and never feel bad about writing sentences explaining what you do. As a teacher, I find it makes assisting students much easier as I see their misconceptions. Best of luck.

Answer 29

LOL OMG YOU ARE FUNNY HAHAHA. Back to the original claim you made. "We are trying to help" I think I helped so..... BYE :)
