Question

Amy and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 7 to the number and

multiplied the surn by 3, it would equal 6. Which equation could Stephanie use to find the number,
A. 3(x + 7) = 6
B. 7(x + 3) = 6
C. 3+ (x + 7) = 6
D. 3(%) + 7 = 6

Answer 1

I believe the answer is A

Answer 2

I would say A. 3(x + 7) = 6. x is the number chosen, and it would be added to 7, so you get x + 7. The sum is then multiplied by 3, so you would put 3 on the outside of the parenthesis, as you always do parenthesis first. Going along with Pemdas-Parenthesis first (or Gemdas-grouping symbols first). Hope this helps!
