Question

2х + 5y = 6
x+2y = -3

what is x?​

Answer 1

x = -3

In-Depth Steps:

1.) Start with the bottom equation:
`x+2y=-3`

2.) Set
`x` alone on one side of the equal sign. Your equation will look like
`3+2y=x`.

3.) Plug
`3+2y` in for
`x` in the first equation. You will get
`2(3+2y)+5y=6`.

4.) Distribute. Your equation now looks like this:
`(6+4y)+5y=6`.

5.) Combine like terms. You will get
`6+9y=6`.

6.) Subtract 6 from both sides. You get
`9y=0`. We can learn that Y=0.

7.) Go back to either equation and put 0 in for y.

8.) In the top equation, it would look like
`2x=6` and the bottom equation would look like
`x=-3`. We basically got our answer of
`x = -3`, but we will plug it into the
`2x=6` equation, and in-fact, we get x = -3.
