Penyelesaian dari 3/2 (x-1)=4 adalah

3/2 (x-1) = 4
3/2 x – 3/2 = 4
3/2 x = 4 + 3/2
3/2 x = 11/2
x = 11/2 x 2/3
x = 22/6
x = 11/3
x = 3 2/3

3/2 ( x-1 ) = 4           —->   [ kedua ruas sama sama dikali 2 ]
2(3/2) ( x – 1 ) = 2 (4)
        3 ( x – 1 ) = 8
             3x – 3 = 8
                  3x = 8 + 3
                  3x = 11
                    x = 11/3
                    x = 3 2/3
