Tohaina
Kua tāruatia ki te papatopenga
-7x+56=4x-21
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x-8.
-7x+56-4x=-21
Tangohia te 4x mai i ngā taha e rua.
-11x+56=-21
Pahekotia te -7x me -4x, ka -11x.
-11x=-21-56
Tangohia te 56 mai i ngā taha e rua.
-11x=-77
Tangohia te 56 i te -21, ka -77.
x=\frac{-77}{-11}
Whakawehea ngā taha e rua ki te -11.
x=7
Whakawehea te -77 ki te -11, kia riro ko 7.
