S Distributive property-The multiplication of two numbers in parentheses by a outside number Step 1: Distribute 4 4(x-3)=20 Problem 1 4.x = 4x Step 2: Remove the constant 4x 12 = 20 +12 +12 4-3-12 4x = 32 math Step 3: Isolate the variable 4x = 32 4 4 Step 4: Solved x = 8 Distributive property 7 - 1 (2a + 3) = 12 Problem 2 Step one: Distribute 1 -1 • 2a = -2a -13-3 Step two: Combine like terms 732a 12 7-3=4 Step three: Remove the constant 4- 2a = 12 -4 -4 -2a = 8 Step four: isolate the variable -2a = 8 -2 -2 Step five: Solved a = -4
