(x+3)/2 = 15
-> 15 * 2 = x +3 = 30
-> 30 -3 = x = 27
-> x = 27

(x+3)/2=15. First multiply everything by 2 so itl be x+3=30, then subtract 3 from both sides, and you get x=27 . Good luck on other problems of this sort.

Multiply both sides by 2, therefore: X + 3 = 30 and X = 27.

Multiply both sides by 2 so
x+ 3 = 30
then take 3 away
x = 27
