Question

1/3 x - 3 = 1

Answer 1

1/3x - 3 = 1 (the first thing to do is get rid of the fraction by multiplying the equation by 3)
(3)1/3x - 3(3) = 1(3) Now multiply....
x - 9 = 3 (now you want to get x on one side by itself, so you have to add 9 to each side)
x - 9 + 9 = 3 + 9
x = 3 + 9
x = 12

check....
1/3x - 3 = 1
1/3(12) - 3 = 1
4 - 3 = 1
1 = 1 (correct)
