5x-15=3\left(x+5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-3.
5x-15=3x+15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+5.
5x-15-3x=15
Tangohia te 3x mai i ngā taha e rua.
2x-15=15
Pahekotia te 5x me -3x, ka 2x.
2x=15+15
Me tāpiri te 15 ki ngā taha e rua.
2x=30
Tāpirihia te 15 ki te 15, ka 30.
x=\frac{30}{2}
Whakawehea ngā taha e rua ki te 2.
x=15
Whakawehea te 30 ki te 2, kia riro ko 15.
