Which is the correct substitution for the system of equations? -3x -16 = x - 2y, -3 (x - 2y) -16 = 18, (-3x - 16) - 2y = 18, x - 2(-3x - 16) = 18

Back

x - 2(-3x - 16) = 18.

Which is the correct substitution for this system? 2(3x -3) = 19, 2x + 5y (3x ) = 19, 2x + 5(3x-3) = 19, 2(3x ) - 3 + 5y = 19

Back

2x + 5(3x-3) = 19.
