Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation: 
2.) Set 
alone on one side of the equal sign. Your equation will look like 
.
3.) Plug 
in for in the first equation. You will get 
.
4.) Distribute. Your equation now looks like this: 
.
5.) Combine like terms. You will get 
.
6.) Subtract 6 from both sides. You get 
. 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 
and the bottom equation would look like 
. We basically got our answer of 
, but we will plug it into the equation, and in-fact, we get x = -3.
Congruent means same so the equation is
5x+24=9x-17
Subtract 5x on both sides
24=4x-17
Add 17 to both sides
41=4x
Divide by 4
