8+2x=-22-8x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4+x.
8+2x+8x=-22
Me tāpiri te 8x ki ngā taha e rua.
8+10x=-22
Pahekotia te 2x me 8x, ka 10x.
10x=-22-8
Tangohia te 8 mai i ngā taha e rua.
10x=-30
Tangohia te 8 i te -22, ka -30.
x=\frac{-30}{10}
Whakawehea ngā taha e rua ki te 10.
x=-3
Whakawehea te -30 ki te 10, kia riro ko -3.
