Steps for solving 3x + 18 = 54 are shown.Explain how Step 1 helps solve the equation.3x+18 = 543x + 18-18 = 54 -183x = 363x_3633X = 12Original equationStep 1Step 2Step 3Step 4) A. Adding 18 to both sides undoes the subtraction.OB. Adding 18 to both sides combines like terms.OC. Subtracting 18 from both sides isolates the variable term.OD. Subtracting 18 from both sides isolates the variable.
Accepted Solution
A:
CBy subtracting 18 to both sides you are separating the 3x because you are not ready to isolate the variable (x) in step 1
