2x+4-5\left(2x-3\right)=3
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+2.
2x+4-10x+15=3
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 2x-3.
-8x+4+15=3
Pahekotia te 2x me -10x, ka -8x.
-8x+19=3
Tāpirihia te 4 ki te 15, ka 19.
-8x=3-19
Tangohia te 19 mai i ngā taha e rua.
-8x=-16
Tangohia te 19 i te 3, ka -16.
x=\frac{-16}{-8}
Whakawehea ngā taha e rua ki te -8.
x=2
Whakawehea te -16 ki te -8, kia riro ko 2.
