-5x+12x-36=-20-9x
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 2x-6.
7x-36=-20-9x
Pahekotia te -5x me 12x, ka 7x.
7x-36+9x=-20
Me tāpiri te 9x ki ngā taha e rua.
16x-36=-20
Pahekotia te 7x me 9x, ka 16x.
16x=-20+36
Me tāpiri te 36 ki ngā taha e rua.
16x=16
Tāpirihia te -20 ki te 36, ka 16.
x=\frac{16}{16}
Whakawehea ngā taha e rua ki te 16.
x=1
Whakawehea te 16 ki te 16, kia riro ko 1.
