18-3x-2\left(x-4\right)=1
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 6-x.
18-3x-2x+8=1
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-4.
18-5x+8=1
Pahekotia te -3x me -2x, ka -5x.
26-5x=1
Tāpirihia te 18 ki te 8, ka 26.
-5x=1-26
Tangohia te 26 mai i ngā taha e rua.
-5x=-25
Tangohia te 26 i te 1, ka -25.
x=\frac{-25}{-5}
Whakawehea ngā taha e rua ki te -5.
x=5
Whakawehea te -25 ki te -5, kia riro ko 5.
