3x-3+4\left(x+3\right)=5x+7-2\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
3x-3+4x+12=5x+7-2\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+3.
7x-3+12=5x+7-2\left(x-3\right)
Pahekotia te 3x me 4x, ka 7x.
7x+9=5x+7-2\left(x-3\right)
Tāpirihia te -3 ki te 12, ka 9.
7x+9=5x+7-2x+6

7x+9=3x+7+6
Pahekotia te 5x me -2x, ka 3x.
7x+9=3x+13
Tāpirihia te 7 ki te 6, ka 13.
7x+9-3x=13
Tangohia te 3x mai i ngā taha e rua.
4x+9=13
Pahekotia te 7x me -3x, ka 4x.
4x=13-9
Tangohia te 9 mai i ngā taha e rua.
4x=4
Tangohia te 9 i te 13, ka 4.
x=\frac{4}{4}
Whakawehea ngā taha e rua ki te 4.
x=1
Whakawehea te 4 ki te 4, kia riro ko 1.
