Example: 5x - 5(2x - 8) = 80
Step 1: Rewrite expression using Distributive Property 5x - 5(2x - 8) = 80 --> -5 times 2x =-10x
Distribute -5 times 2x and -5 times -8 -5 times -8 = 40
Step 2: Combine like terms 5x - 10x + 40 = 80 --> 5x and -10x = -5x
5x and -10x can be combined.
Step 3: Add or Subtract (Cancel the Constant) -5x + 40 = 80 --> 80 - 40 = 40
Since the constant is +40, we will subtract 40 to cancel it out.
Step 4: Divide or Multiply (Cancel the Coefficient) -5x = 40 --> 40 divided by -5 = -8
Since the X is being "multiplied" by -5, we will divide by -5
x = -8
