A variable needs to be eliminated to solve the system of equations below. Choose the correct first step.
minus, 4, x, plus, y, equals, minus, 35
−4x+y=
−35
minus, 2, x, minus, y, equals, minus, 7
−2x−y=
−7
The correct first step to eliminate a variable in this system of equations is to multiply the first equation by 2.
By doing so, the system of equations becomes:
-8x + 2y = -70
-2x - y = -7
