2x-7+3x=2x-8
Tangohia te 3 i te -4, ka -7.
5x-7=2x-8
Pahekotia te 2x me 3x, ka 5x.
5x-7-2x=-8
Tangohia te 2x mai i ngā taha e rua.
3x-7=-8
Pahekotia te 5x me -2x, ka 3x.
3x=-8+7
Me tāpiri te 7 ki ngā taha e rua.
3x=-1
Tāpirihia te -8 ki te 7, ka -1.
x=\frac{-1}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{1}{3}
Ka taea te hautanga \frac{-1}{3} te tuhi anō ko -\frac{1}{3} mā te tango i te tohu tōraro.
