Question

2х + 5y = 6x+2y = -3 what is x?​

Answer 1

Answer:

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.
