Answer: correct reason for statement #2-C
correct reason for statement #3-B
correct reason for statement #4-A
correct reason for statement #5-D
Step-by-step explanation:
correct reason for statement #2-C
3(x+2)=3x+6 it is the distributive property
correct reason for statement #3-B
3x+6+1=3x+7 ,we are combining the like terms i.e. we have combined the constant term and 3x has been left as it is
correct reason for statement #4-A
3x+7=8 ⇒ 3x=8-7=1 it is the subtraction property of equality since we are subtracting by 7 on both sides
correct reason for statement #5-D
3x=1 ⇒ x=1/3 it is division property of equality since we are dividing by 3 on both sides
