24-6x-55=-5\left(2x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 4-x.
-31-6x=-5\left(2x+3\right)
Tangohia te 55 i te 24, ka -31.
-31-6x=-10x-15
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 2x+3.
-31-6x+10x=-15
Me tāpiri te 10x ki ngā taha e rua.
-31+4x=-15
Pahekotia te -6x me 10x, ka 4x.
4x=-15+31
Me tāpiri te 31 ki ngā taha e rua.
4x=16
Tāpirihia te -15 ki te 31, ka 16.
x=\frac{16}{4}
Whakawehea ngā taha e rua ki te 4.
x=4
Whakawehea te 16 ki te 4, kia riro ko 4.
