Kua tāruatia ki te papatopenga
15x-60=12+7x-37
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-4.
15x-60=-25+7x
Tangohia te 37 i te 12, ka -25.
15x-60-7x=-25
Tangohia te 7x mai i ngā taha e rua.
8x-60=-25
Pahekotia te 15x me -7x, ka 8x.
8x=-25+60
Me tāpiri te 60 ki ngā taha e rua.
8x=35
Tāpirihia te -25 ki te 60, ka 35.
x=\frac{35}{8}
Whakawehea ngā taha e rua ki te 8.
