Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3x+5.

$$12x+20-3\left(4-2x\right)=-28$$

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 4-2x.

$$12x+20-12+6x=-28$$

Tangohia te 12 i te 20, ka 8.

$$12x+8+6x=-28$$

Pahekotia te 12x me 6x, ka 18x.

$$18x+8=-28$$

Tangohia te 8 mai i ngā taha e rua.

$$18x=-28-8$$

Tangohia te 8 i te -28, ka -36.

$$18x=-36$$

Whakawehea ngā taha e rua ki te 18.

$$x=\frac{-36}{18}$$

Whakawehea te -36 ki te 18, kia riro ko -2.

$$x=-2$$
