y=2x-7
3x+2y=12
To find out if (2, -3) is your answer we have to plug it in and see if it works.
xvalue= 2
yvalue= -3
-3 = 2(2)-7
-3 = -3 .... This one works
Now for the next equation
3(2) + 2(-3) = 12
0 DOES NOT EQUAL 12
THEREFORE, NO. (2, -3) is not a solution

The point (2,-3) means that x = 2 and y = -3.
Plug those values into both equations and simplify. If you get the same answer on both sides of the equations given, then the given point is a solution to the system of linear equations.
