2x+2-5x=3
Tangohia te 5x mai i ngā taha e rua.
-3x+2=3
Pahekotia te 2x me -5x, ka -3x.
-3x=3-2
Tangohia te 2 mai i ngā taha e rua.
-3x=1
Tangohia te 2 i te 3, 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.
