Answer:
x=57
Step-by-step explanation:
1/3x - 1/2 = 18 1/2
first, combine 1/3 and x to get x/3
then, convert 18 1/2 into an improper fraction.
x/3 - 1/2 = 37/2
next, we need to isolate the variable by adding 1/2 to both sides
x/3 = (1+37)/2
x/3 = 38/2
x/3 = 19
now, we have to do the opposite of what's happening to the variable, so since the variable is in a fraction we multiply both sides by 3 to isolate x
3(x/3) = 3(19)
x=57
