Question

If you take a number, times by 3 then add 5. You get the same as if you took the number, times by 7 then subtract 8. What is the number?

Answer 1

Answer: x = 13/4

Explanation:

Easy, let's use x to define the number:

3x + 5 = 7x - 8

We take the 3x to the other side:

5 = 4x - 8

We take the 8 to the other side:

13 = 4x

x = 13/4
