10-2x+6=3x-4\left(5-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-3.
16-2x=3x-4\left(5-x\right)
Tāpirihia te 10 ki te 6, ka 16.
16-2x=3x-20+4x
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te 5-x.
16-2x=7x-20
Pahekotia te 3x me 4x, ka 7x.
16-2x-7x=-20
Tangohia te 7x mai i ngā taha e rua.
16-9x=-20
Pahekotia te -2x me -7x, ka -9x.
-9x=-20-16
Tangohia te 16 mai i ngā taha e rua.
-9x=-36
Tangohia te 16 i te -20, ka -36.
x=\frac{-36}{-9}
Whakawehea ngā taha e rua ki te -9.
x=4
Whakawehea te -36 ki te -9, kia riro ko 4.
