5x-1.5=3x-3.5-5
Tāpirihia te -3.5 ki te 2, ka -1.5.
5x-1.5=3x-8.5
Tangohia te 5 i te -3.5, ka -8.5.
5x-1.5-3x=-8.5
Tangohia te 3x mai i ngā taha e rua.
2x-1.5=-8.5
Pahekotia te 5x me -3x, ka 2x.
2x=-8.5+1.5
Me tāpiri te 1.5 ki ngā taha e rua.
2x=-7
Tāpirihia te -8.5 ki te 1.5, ka -7.
x=\frac{-7}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{7}{2}
Ka taea te hautanga \frac{-7}{2} te tuhi anō ko -\frac{7}{2} mā te tango i te tohu tōraro.
