9x+17-9=10\left(17-x\right)+x
Pahekotia te 10x me -x, ka 9x.
9x+8=10\left(17-x\right)+x
Tangohia te 9 i te 17, ka 8.
9x+8=170-10x+x
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te 17-x.
9x+8=170-9x
Pahekotia te -10x me x, ka -9x.
9x+8+9x=170
Me tāpiri te 9x ki ngā taha e rua.
18x+8=170
Pahekotia te 9x me 9x, ka 18x.
18x=170-8
Tangohia te 8 mai i ngā taha e rua.
18x=162
Tangohia te 8 i te 170, ka 162.
x=\frac{162}{18}
Whakawehea ngā taha e rua ki te 18.
x=9
Whakawehea te 162 ki te 18, kia riro ko 9.
