-11x-77+639=11+12
Whakamahia te āhuatanga tohatoha hei whakarea te -11 ki te x+7.
-11x+562=11+12
Tāpirihia te -77 ki te 639, ka 562.
-11x+562=23
Tāpirihia te 11 ki te 12, ka 23.
-11x=23-562
Tangohia te 562 mai i ngā taha e rua.
-11x=-539
Tangohia te 562 i te 23, ka -539.
x=\frac{-539}{-11}
Whakawehea ngā taha e rua ki te -11.
x=49
Whakawehea te -539 ki te -11, kia riro ko 49.
