Question

Thu wants to play "guess my number" she states, "when i triple my number and add 5, i get 26. What is my numer" wht is her number shiw how you know

Answer 1

Let's say x is the number.
She's going to triple it (3x) then add 5 (+5) to it. The answer will be 26.

3x + 5 = 26
Subtract 5 from both sides.
3x = 21
Divide 3 from both sides.
x = 7

Her number is 7.
