2+1.4x-2.8=10.4
Whakamahia te āhuatanga tohatoha hei whakarea te x-2 ki te 1.4.
-0.8+1.4x=10.4
Tangohia te 2.8 i te 2, ka -0.8.
1.4x=10.4+0.8
Me tāpiri te 0.8 ki ngā taha e rua.
1.4x=11.2
Tāpirihia te 10.4 ki te 0.8, ka 11.2.
x=\frac{11.2}{1.4}
Whakawehea ngā taha e rua ki te 1.4.
x=\frac{112}{14}
Whakarohaina te \frac{11.2}{1.4} mā te whakarea i te taurunga me te tauraro ki te 10.
x=8
Whakawehea te 112 ki te 14, kia riro ko 8.
