5x-10+3=7-3\left(2x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-2.
5x-7=7-3\left(2x+1\right)
Tāpirihia te -10 ki te 3, ka -7.
5x-7=7-6x-3
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 2x+1.
5x-7=4-6x
Tangohia te 3 i te 7, ka 4.
5x-7+6x=4
Me tāpiri te 6x ki ngā taha e rua.
11x-7=4
Pahekotia te 5x me 6x, ka 11x.
11x=4+7
Me tāpiri te 7 ki ngā taha e rua.
11x=11
Tāpirihia te 4 ki te 7, ka 11.
x=\frac{11}{11}
Whakawehea ngā taha e rua ki te 11.
x=1
Whakawehea te 11 ki te 11, kia riro ko 1.
