Solving Multi-step Equations Variables on Both Sides and Ratio and Proportion

More on Ratio & Proportion (6) (z + 3) = (z – 4) (6 z + 18) = (4 z – 16) -4 z 2 z + 18 = – 16 -18 2 z = -34 9/10/2020 www. numberbender. com 2 z = -34 2 2 z = -17 2

Your Turn (3) (m – 2) = (m + 4) (5) 3 m – 6 = 5 m + 20 -2 m = 26 -2 -2 m = -13 9/10/2020 www. numberbender. com 3

More on Ratio & Proportions (w - 4) 3 = 5 (w + 6) 3 w – 12 = 5 w + 30 -5 w -2 w – 12 = 30 +12 -2 w = 42 9/10/2020 www. numberbender. com -2 w = 42 -2 -2 w = -21 4

Algebraic Procedures Cross Multiplication (6) (z + 3) = (z – 4) (6 z + 18) = (4 z – 16) -4 z 2 z + 18 = – 16 -18 2 z = -34 2 z = -34 2 2 Distributive Property Subtract 4 z on both sides Subtract 18 on both sides Divide 2 on both sides z = -17 9/10/2020 www. numberbender. com 5

Your Turn Solve for b (2) 2 A = bh h h Multiply 2 on both sides Divide h on both sides 9/10/2020 www. numberbender. com 6
