2x+3-5x-2=8
Hei kimi i te tauaro o 5x+2, kimihia te tauaro o ia taurangi.
-3x+3-2=8
Pahekotia te 2x me -5x, ka -3x.
-3x+1=8
Tangohia te 2 i te 3, ka 1.
-3x=8-1
Tangohia te 1 mai i ngā taha e rua.
-3x=7
Tangohia te 1 i te 8, ka 7.
x=\frac{7}{-3}
Whakawehea ngā taha e rua ki te -3.
x=-\frac{7}{3}
Ka taea te hautanga \frac{7}{-3} te tuhi anō ko -\frac{7}{3} mā te tango i te tohu tōraro.
