Solving Multi Step Equations

Distributive Property Check! 2(x + 1) = 8 2(x + 1) = 8 2(3 + 1) = 8 2x + 2 = 8 - 2 - 2 2(4) = 8 2x = 6 2x = 6 2 2 8 = 8  x = 3

Distributive Property Check! 5(x - 4) = -10 5(x - 4) = -10 5(2 - 4) = -10 5x - 20 = -10 + 20 + 20 5(-2) = -10 5x = 10 5x = 10 5 5 -10 = -10  x = 2

Distributive Property Check! -3(x - 5) = 12 -3(x - 5) = 12 -3(1 - 5) = 12 -3x + 15 = 12 - 15 -15 -3(-4) = 12 -3x = -3 -3x = -3 -3 -3 12 = 12  = 12 x = 1

Distributive Property Check! 4(2x + 1) = -4 4(2x +1) = -4 4(2(-1) + 1) = -4 8x + 4 = -4 4(-2 + 1) = -4 -4 -4 8x = -8 8x = -3 4(-1) = -4 8 8 -4 = -4  x = -1

Distributive Property Check! 6(-2x + 3) = -6 6(-2x +3) = -6 6(-2(2) + 3) = -6 -12x + 18 = -6 6(-4 + 3) = -6 -18 -18 -12x = -24 -12x = -24 6(-1) = -6 -12 -12 = 12 -6 = -6  x = 2

Distributive Property Check! (x + 5)3 = -3 (x + 5)3 = -3 (-6 + 5)3 = -3 3x + 15 = -3 (-1)3 = -3 -15 -15 3x = -18 3x = -18 -6 = -6  3 3 = 12 x = -6

Distributive Property Check! 1 1 (x - 6) = 1 (x - 6) = 1 2 2 1 1 x (8 - 6) = 1 - 3 = 1 2 2 +3 +3 1 2 (2) = 1 2 1 x = 4 2 1 1 2 1 = 1  x = 8
