-4x+30=23x+759
Whakamahia te āhuatanga tohatoha hei whakarea te 23 ki te x+33.
-4x+30-23x=759
Tangohia te 23x mai i ngā taha e rua.
-27x+30=759
Pahekotia te -4x me -23x, ka -27x.
-27x=759-30
Tangohia te 30 mai i ngā taha e rua.
-27x=729
Tangohia te 30 i te 759, ka 729.
x=\frac{729}{-27}
Whakawehea ngā taha e rua ki te -27.
x=-27
Whakawehea te 729 ki te -27, kia riro ko -27.
