Consider the system of equations
5x - y = 31
-3x + 4y = -37
Substitute this into the second equation: y = 5x - 31
Solve for x and y, enter your answer as an ordered pair(x,y)
Im not sure what subsituting it into the third equation, but the answer to the first system of equation is
(87/17, -92/17). Hopes this helps
