Consider the system of equations
5x+y=31,−3x+4y=−37.
solve the first equation for y in terms of x
enter your answer in the form of "y= ..."
Isolate y:
y = -5x + 31
If you want to solve the entire system of equations, multiple E1 by 3, and E2 by 5
15x + 3y = 93
-15x + 20y = -185
Adding both equations I obtain:
23y = -92
y = -4
x = 7
(x, y) = (7, -4)
