-12+4x=2\left(2x-5\right)-\left(3-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 6-2x.
-12+4x=4x-10-\left(3-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-5.
-12+4x=4x-10-3-\left(-x\right)
Hei kimi i te tauaro o 3-x, kimihia te tauaro o ia taurangi.
-12+4x=4x-10-3+x
Ko te tauaro o -x ko x.
-12+4x=4x-13+x
Tangohia te 3 i te -10, ka -13.
-12+4x=5x-13
Pahekotia te 4x me x, ka 5x.
-12+4x-5x=-13
Tangohia te 5x mai i ngā taha e rua.
-12-x=-13
Pahekotia te 4x me -5x, ka -x.
-x=-13+12
Me tāpiri te 12 ki ngā taha e rua.
-x=-1
Tāpirihia te -13 ki te 12, ka -1.
x=1
Me whakarea ngā taha e rua ki te -1.
