4x-12=9x+18
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
4x-12-9x=18
Tangohia te 9x mai i ngā taha e rua.
-5x-12=18
Pahekotia te 4x me -9x, ka -5x.
-5x=18+12
Me tāpiri te 12 ki ngā taha e rua.
-5x=30
Tāpirihia te 18 ki te 12, ka 30.
x=\frac{30}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-6
Whakawehea te 30 ki te -5, kia riro ko -6.
