5x-15=6-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-3.
5x-15+2x=6
Me tāpiri te 2x ki ngā taha e rua.
7x-15=6
Pahekotia te 5x me 2x, ka 7x.
7x=6+15
Me tāpiri te 15 ki ngā taha e rua.
7x=21
Tāpirihia te 6 ki te 15, ka 21.
x=\frac{21}{7}
Whakawehea ngā taha e rua ki te 7.
x=3
Whakawehea te 21 ki te 7, kia riro ko 3.
