Question

Find a number such that the ratio of 3 times that number and 5 is equal to the difference between that number and 2.

Answer 1

5

Explanation:

let x represent the number

3x : 5 = x - 2

3x / 5 = x - 2

cross multiply

3x = 5 ( x - 2)

3x = 5x - 10

3x - 5x = -10

-2x = -10

Divide both sides by - 2

x = 5
