2x-6+3\left(x-2\right)=18
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
2x-6+3x-6=18
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
5x-6-6=18
Pahekotia te 2x me 3x, ka 5x.
5x-12=18
Tangohia te 6 i te -6, ka -12.
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.
