Kua tāruatia ki te papatopenga
15-\left(3x+2\right)=5
Whakareatia ngā taha e rua o te whārite ki te 5.
15-3x-2=5
Hei kimi i te tauaro o 3x+2, kimihia te tauaro o ia taurangi.
13-3x=5
Tangohia te 2 i te 15, ka 13.
-3x=5-13
Tangohia te 13 mai i ngā taha e rua.
-3x=-8
Tangohia te 13 i te 5, ka -8.
x=\frac{-8}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{8}{3}
Ka taea te hautanga \frac{-8}{-3} te whakamāmā ki te \frac{8}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
