Whakareatia te 0 ki te 85, ka 0.

$$0\left(x+45\right)\times 8=\left(x+45-35\right)\times 12$$

Whakareatia te 0 ki te 8, ka 0.

$$0\left(x+45\right)=\left(x+45-35\right)\times 12$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0=\left(x+45-35\right)\times 12$$

Tangohia te 35 i te 45, ka 10.

$$0=\left(x+10\right)\times 12$$

Whakamahia te āhuatanga tohatoha hei whakarea te x+10 ki te 12.

$$0=12x+120$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$12x+120=0$$

Tangohia te 120 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$12x=-120$$

Whakawehea ngā taha e rua ki te 12.

$$x=\frac{-120}{12}$$

Whakawehea te -120 ki te 12, kia riro ko -10.

$$x=-10$$
