Answer:
answer is option B
Step-by-step explanation:
ok the equation is 2/3 x +9 = 15
if we substract 9 from both sides it becomes, 2/3x +9-9 = 15-9.
2/3x = 6
now if we multiply both sides by the reciprocal of 2/3 ( reciprocal means flip it for example receprocal or 2/3 is 3/2)
we multiply both side by reciprocal ie,
2/3 x 3/2 which is 1 because the 3 on the numerator cancels with the 3 on the deniy and the 2 on the numerator cancels with 2 on the denominator. then you are left with only x on the left side.
x = 6 x 3/2 = 18/2 = 9.
