step work justification
step1: 3(x + 2) = 12 = given
step2:
step3: 3x + 6 − 6 = 12 − 6 = subtraction property of equality
step4: 3x = 6 = simplify
step: 5 three times x over three equals six over three= division property of equality
step6: x = 2 = simplify
a. 3x + 6 = 12; distributive property
b. 3x + 2 = 12; distributive property
c. 3x + 6 = 12; multiplication property of equality
d. 3x + 2 = 12; multiplication property of equality
