4x-14+7x=3x+2
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te 2-x.
11x-14=3x+2
Pahekotia te 4x me 7x, ka 11x.
11x-14-3x=2
Tangohia te 3x mai i ngā taha e rua.
8x-14=2
Pahekotia te 11x me -3x, ka 8x.
8x=2+14
Me tāpiri te 14 ki ngā taha e rua.
8x=16
Tāpirihia te 2 ki te 14, ka 16.
x=\frac{16}{8}
Whakawehea ngā taha e rua ki te 8.
x=2
Whakawehea te 16 ki te 8, kia riro ko 2.
