21-35-\left(-3x\right)=19
Hei kimi i te tauaro o 35-3x, kimihia te tauaro o ia taurangi.
21-35+3x=19
Ko te tauaro o -3x ko 3x.
-14+3x=19
Tangohia te 35 i te 21, ka -14.
3x=19+14
Me tāpiri te 14 ki ngā taha e rua.
3x=33
Tāpirihia te 19 ki te 14, ka 33.
x=\frac{33}{3}
Whakawehea ngā taha e rua ki te 3.
x=11
Whakawehea te 33 ki te 3, kia riro ko 11.
