17-3x+15=2-13x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-5.
32-3x=2-13x
Tāpirihia te 17 ki te 15, ka 32.
32-3x+13x=2
Me tāpiri te 13x ki ngā taha e rua.
32+10x=2
Pahekotia te -3x me 13x, ka 10x.
10x=2-32
Tangohia te 32 mai i ngā taha e rua.
10x=-30
Tangohia te 32 i te 2, ka -30.
x=\frac{-30}{10}
Whakawehea ngā taha e rua ki te 10.
x=-3
Whakawehea te -30 ki te 10, kia riro ko -3.
