Question

Thu wants to play “Guess My Number,"she states. “When I triple my number and add five ,I get twenty-six.what is my number?" What is her number? Show how you know

Answer 1

Her number is 7. You simply subtract 5 from 26 and get 21 then you divide it by 3 and get 7. Basically you are reversing the steps she stated.

Answer 2

3x + 5=26
subtract 5 from both sides
3x=21
divide by 3
x=7
