Kua tāruatia ki te papatopenga
\left(-12+4.8\right)x-2=\frac{56}{2}
Whakawehea ngā taha e rua ki te 2.
\left(-12+4.8\right)x-2=28
Whakawehea te 56 ki te 2, kia riro ko 28.
-7.2x-2=28
Tāpirihia te -12 ki te 4.8, ka -7.2.
-7.2x=28+2
Me tāpiri te 2 ki ngā taha e rua.
-7.2x=30
Tāpirihia te 28 ki te 2, ka 30.
x=\frac{30}{-7.2}
Whakawehea ngā taha e rua ki te -7.2.
x=\frac{300}{-72}
Whakarohaina te \frac{30}{-7.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-\frac{25}{6}
Whakahekea te hautanga \frac{300}{-72} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
