Question

how do you solve this equation (in the comments)

Answer 1

how do you solve: \[3y + \frac{1}{4} y=26\] I can't remember

Answer 2

add the y terms

Answer 3

What is 3 + 1/4?

Answer 4

3y and 1/4y are like terms because they both only have one y. So you can combine them. :)

Answer 5

\[3\frac{1}{4}\]

Answer 6

Make sure to add the y. :)

Answer 7

How would i find the y then?

Answer 8

So your equation looks like: \[\large \large 3 \frac{ 1 }{ 4 }y = 26\] To solve for y, you want to divide both side by 3 1/4.
3 1/4 y divided by 3 1/4 would give you 1y or just y.
26 divided by 3 1/4 would give you a number.
That number would be equal to y.

Answer 9

That makes NO sense to me what so ever. >.<

Answer 10

How so? Explain what's confusing you. :)

Answer 11

you can't divide a fractional number by a fraction, can you?

Answer 12

You can. You can convert the fractions into a decimals.
Then you can divide the decimal by the decimal.
Make sense? o.o.

Answer 13

Nvm, i got it.

Answer 14

Or you can use the method, KFC. (Keep Flip Change)

Answer 15

The answer is 8.

Answer 16

KCF* (Keep Change Flip) Thinking about that chicken. >_>

Answer 17

Haha. easy to get confused with.

Answer 18

Correct. :)

Answer 19

You can check your work by plugging it in:
3(8) + 1/4(8) = 26

3 * 8 = 24

1/4 * 8 = 2

24 + 2 = 26

So the answer is 8. :)

Answer 20

Question: check my work please: \[5[1- 2(x+2)=4x\]\[5[1-2x-4]=4x\]\[5-10x-20=4x\]\[-15=14x\] Is that right?

Answer 21

@GoldPhenoix Little help please?

Answer 22

At: 5[ 1 - 2x - 4] = 4x
You still didn't finish the one in the parenthesis.
You have like terms that you can combine.

Answer 23

oh, so it would be -3 instead of 4?

Answer 24

I got 2=6x, is that right?

Answer 25

Yes. 1-4 = -3. So after fixing that mistake, your equation should look like:
5 [-2x -3] = 4x

Answer 26

Now what would you do next?

Answer 27

oh fail. okay. I get it. after that, you would of gotten: \[-10x-15=4x\] right?

Answer 28

Correct!

Answer 29

That would still leave me with 15=14x thought.

Answer 30

Ooh. My bad. >_>

Answer 31

So yes, you are correct. Make sure to divide both side by 14. to get x. :)

Answer 32

but what would it be though?

Answer 33

Hmm.
14x / 14 = x
-15 / 14 = -1.07 (Rounded)
Or you can just leave it as: \[\large \large \frac{ -15 }{ 14 } = x\]

Answer 34

thanks.
