5x-30=2x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-6.
5x-30-2x=0
Tangohia te 2x mai i ngā taha e rua.
3x-30=0
Pahekotia te 5x me -2x, ka 3x.
3x=30
Me tāpiri te 30 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{30}{3}
Whakawehea ngā taha e rua ki te 3.
x=10
Whakawehea te 30 ki te 3, kia riro ko 10.
