Steps for solving 4x - 12 = 20 are shown. Explain how Step 3 helps solve the equation. 4x-12-20 Original equation 4x- 12+12-20 +12 Step 1 4x - 32 Step 2 4x 32 Step 3 4 4 X-8 Step 4 A. Dividing both sides by 4 eliminates the variable. B. Multiplying both sides by 4 isolates the variable. C. Dividing both sides by 4 isolates the variable. O D. Multiplying both sides by 4 undoes the division.
