4x+70=11x
Pahekotia te 3x me x, ka 4x.
4x+70-11x=0
Tangohia te 11x mai i ngā taha e rua.
-7x+70=0
Pahekotia te 4x me -11x, ka -7x.
-7x=-70
Tangohia te 70 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-70}{-7}
Whakawehea ngā taha e rua ki te -7.
x=10
Whakawehea te -70 ki te -7, kia riro ko 10.
