3

Answer 1

so, where do you get stuck? If you just want verification of your answer, show us whatcha got.

If you are having trouble, show us how far you get.

Answer 2

Distribute the 1/3.
1/3(x-1)= 4
1/3x - 1/3 = 4
Add 1/3 rd to get rid of it.
1/3x = 4 + 1/3
Divide 1/3x by 4+1/3
x=????

Answer 3

After you get to

1/3x = 4 + 1/3

combine the right side to get

1/3 x = 13/3

Now divide by 1/3 to get

x = 13/3 ÷ 1/3 = 13/3 * 3/1 = 13
x=13

Just for reference, it is usually easier to get rid of the fractions as soon as possible. In this case,

1/3 (x-1) = 4
multiply by 3 to get
(x-1) = 4*3
x-1 = 12
x = 13
