Question

What is the solution to the system of equations?
5x+4y=8
x-2y=10

Answer 1

Do you have answer choices we can build off of? c:

Answer 2

no sadly

Answer 3

Alright no biggie :) Do you have any idea what the answers may be?

Answer 4

If not then let's move on :P

Answer 5

ok yes lets move on because i have no idea

Answer 6

Let me help you if you like?

Answer 7

Okay I love these!

Answer 8

Answer 9

Okay so lets do this!

Answer 10

please =)

Answer 11

I got it but could you help make sure my explanations are correct? O.o

Answer 12

Sure haha.

Answer 13

These are the best :)

Answer 14

Alright, so

5x+4y=8
x-2y=10

The first step is to multiply everything by 2 except for the end numbers (the equal sign will be the 'boundary')
5x+4y=8
2x-4y=10

Answer 15

No sorry..

Answer 16

Thats wrong..

Answer 17

oh ok then

Answer 18

It's not wrong

Answer 19

The first step is to subtract 2y from each side on the second equation.

Answer 20

Its much easier that way.

Answer 21

Then you multiply:

When you do that you should get:

\[x = 2(y + 5)\]

Answer 22

so now we know what x is..

Answer 23

one sec

Answer 24

Then you have to plug in x into the first equation...

so we would have:

\[5(2y +10) + 4y = 8 \]

Answer 25

When you solve you should get:

\[y = -3\]

Answer 26

If we add my equation we get 7x=28 and x=4.
4-2y = 10
-2y = 10 - 4
-2y = 6 = -3

y = 3
x = 4

Answer 27

ok now how do i find x

Answer 28

Now plug in y into this equation:

\[x = 2(y + 5)\]

Answer 29

wait so is it 3 or -3

Answer 30

y = -3 sorry, I forgot that

Answer 31

So you would solve this to get x:

\[x = 2(-3 + 5)\]

Answer 32

oh ok

Answer 33

oh ok which would be...give me a sec

Answer 34

Now when you do that you should get:

\[x = 4\]

Answer 35

so the answer is:

\[(4, -3)\]

Answer 36
