2x-3x-3=4\left(x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x+1.
-x-3=4\left(x+3\right)
Pahekotia te 2x me -3x, ka -x.
-x-3=4x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+3.
-x-3-4x=12
Tangohia te 4x mai i ngā taha e rua.
-5x-3=12
Pahekotia te -x me -4x, ka -5x.
-5x=12+3
Me tāpiri te 3 ki ngā taha e rua.
-5x=15
Tāpirihia te 12 ki te 3, ka 15.
x=\frac{15}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-3
Whakawehea te 15 ki te -5, kia riro ko -3.
