4x-540=x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-135.
4x-540-x=0
Tangohia te x mai i ngā taha e rua.
3x-540=0
Pahekotia te 4x me -x, ka 3x.
3x=540
Me tāpiri te 540 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{540}{3}
Whakawehea ngā taha e rua ki te 3.
x=180
Whakawehea te 540 ki te 3, kia riro ko 180.
