3y-2=7y+1
Pahekotia te y me 6y, ka 7y.
3y-2-7y=1
Tangohia te 7y mai i ngā taha e rua.
-4y-2=1
Pahekotia te 3y me -7y, ka -4y.
-4y=1+2
Me tāpiri te 2 ki ngā taha e rua.
-4y=3
Tāpirihia te 1 ki te 2, ka 3.
y=\frac{3}{-4}
Whakawehea ngā taha e rua ki te -4.
y=-\frac{3}{4}
Ka taea te hautanga \frac{3}{-4} te tuhi anō ko -\frac{3}{4} mā te tango i te tohu tōraro.
