Help me solve ;;;;; FCC Solving equations

(12 + x)/3 = 5
Multiply each side by 3 :
12 + x = 15
Subtract 12 from each side:
x = 3
x/3 - 5 = 3
Multiply each side by 3 :
x - 15 = 9
Add 15 to each side:
x = 24

To solve equations, multiply or divide to eliminate fractions, and then add or subtract to isolate the variable. For example, from the equation 3 12 + x ​ = 5 , we find x = 3 after simplifying. Similarly, in 3 x ​ − 5 = 3 , we obtain x = 24 through similar steps.
