5.3x-2.2x-6.6=12
Whakamahia te āhuatanga tohatoha hei whakarea te -2.2 ki te x+3.
3.1x-6.6=12
Pahekotia te 5.3x me -2.2x, ka 3.1x.
3.1x=12+6.6
Me tāpiri te 6.6 ki ngā taha e rua.
3.1x=18.6
Tāpirihia te 12 ki te 6.6, ka 18.6.
x=\frac{18.6}{3.1}
Whakawehea ngā taha e rua ki te 3.1.
x=\frac{186}{31}
Whakarohaina te \frac{18.6}{3.1} mā te whakarea i te taurunga me te tauraro ki te 10.
x=6
Whakawehea te 186 ki te 31, kia riro ko 6.
