18x+6=-6\left(x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 3x+1.
18x+6=-6x-18
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x+3.
18x+6+6x=-18
Me tāpiri te 6x ki ngā taha e rua.
24x+6=-18
Pahekotia te 18x me 6x, ka 24x.
24x=-18-6
Tangohia te 6 mai i ngā taha e rua.
24x=-24
Tangohia te 6 i te -18, ka -24.
x=\frac{-24}{24}
Whakawehea ngā taha e rua ki te 24.
x=-1
Whakawehea te -24 ki te 24, kia riro ko -1.
