Which is the best first step and explanation for solving this system of equations? 3x + 4y = 12
3x = 2y - 8
CE
IC
3x + 4y + 3x = 12 + 2y - 8
Add the two equations to one another.
3x + 4y - (3x) = 12 - (2y - 8)
Subtract the second equation
from the first equation
9x + 12y = 36
3x + 4y - 8 = 12 - 8
Multiply both sides of
the first equation by 3.
Subtract an equal amount from
both sides of the first equation
