95=3-24x-18+2x
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te 4x+3.
95=-15-24x+2x
Tangohia te 18 i te 3, ka -15.
95=-15-22x
Pahekotia te -24x me 2x, ka -22x.
-15-22x=95
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-22x=95+15
Me tāpiri te 15 ki ngā taha e rua.
-22x=110
Tāpirihia te 95 ki te 15, ka 110.
x=\frac{110}{-22}
Whakawehea ngā taha e rua ki te -22.
x=-5
Whakawehea te 110 ki te -22, kia riro ko -5.
