I am thinking of a number. If you multiply my number by 5, add - 12 to the product, and then take 1/2 of the sum, the result is 14. Find my number.

14x2=28

28+12=40

40/5=8

(2n - 12) / 2 = 14

Five times the number subtracted by 12, divided by 2 is equivalent to 14.

Multiply both sides by 2:

2n - 12 = 28

Add 12 to both sides:

2n = 40

n = 20

The number is 20
