Answer:
x = -4, y = 3
Step-by-step explanation:
In one equation (let's use the top one), solve for one of the variables (let's solve for y first).
5x - 2y = - 26 --> -2y = -5x - 26 --> y = (5/2)x + 13
Now, substitute ((5/2)x + 13) in for y in the second equation.
-7x + 4((5/2)x + 13) = 40 --> -7x + 10x + 52= 40 --> 3x = -12 --> x = -4
Then, subtitute that in to one of the equations.
5(-4) - 2y = -26 --> -20 - 2y = -26 --> -2y = -6 --> y = 3
