Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te a-5.

$$3a-15=2\left(6+a\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 6+a.

$$3a-15=12+2a$$

Tangohia te 2a mai i ngā taha e rua.

$$3a-15-2a=12$$

Pahekotia te 3a me -2a, ka a.

$$a-15=12$$

Me tāpiri te 15 ki ngā taha e rua.

$$a=12+15$$

Tāpirihia te 12 ki te 15, ka 27.
