12x+8x-24=136
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x-12.
20x-24=136
Pahekotia te 12x me 8x, ka 20x.
20x=136+24
Me tāpiri te 24 ki ngā taha e rua.
20x=160
Tāpirihia te 136 ki te 24, ka 160.
x=\frac{160}{20}
Whakawehea ngā taha e rua ki te 20.
x=8
Whakawehea te 160 ki te 20, kia riro ko 8.
