Which is the correct substitution for the system of equations? 2x - 10 = -4x + 8, 2(-4x + 8) - 10 = 8, -4(2x - 10) = 8, -4x + 8 + 2x = 10

Back

2x - 10 = -4x + 8

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
