2x+10=-4\left(2x-2\right)+2x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+5.
2x+10=-8x+8+2x
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te 2x-2.
2x+10=-6x+8
Pahekotia te -8x me 2x, ka -6x.
2x+10+6x=8
Me tāpiri te 6x ki ngā taha e rua.
8x+10=8
Pahekotia te 2x me 6x, ka 8x.
8x=8-10
Tangohia te 10 mai i ngā taha e rua.
8x=-2
Tangohia te 10 i te 8, ka -2.
x=\frac{-2}{8}
Whakawehea ngā taha e rua ki te 8.
x=-\frac{1}{4}
Whakahekea te hautanga \frac{-2}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
