Kua tāruatia ki te papatopenga
2\left(1\times 2+1\right)-8y=1
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.
2\left(2+1\right)-8y=1
Whakareatia te 1 ki te 2, ka 2.
2\times 3-8y=1
Tāpirihia te 2 ki te 1, ka 3.
6-8y=1
Whakareatia te 2 ki te 3, ka 6.
-8y=1-6
Tangohia te 6 mai i ngā taha e rua.
-8y=-5
Tangohia te 6 i te 1, ka -5.
y=\frac{-5}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{5}{8}
Ka taea te hautanga \frac{-5}{-8} te whakamāmā ki te \frac{5}{8} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
