2x+8=18-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+4.
2x+8+3x=18
Me tāpiri te 3x ki ngā taha e rua.
5x+8=18
Pahekotia te 2x me 3x, ka 5x.
5x=18-8
Tangohia te 8 mai i ngā taha e rua.
5x=10
Tangohia te 8 i te 18, ka 10.
x=\frac{10}{5}
Whakawehea ngā taha e rua ki te 5.
x=2
Whakawehea te 10 ki te 5, kia riro ko 2.
