1.8x=2.4x+4.8
Whakamahia te āhuatanga tohatoha hei whakarea te 2.4 ki te x+2.
1.8x-2.4x=4.8
Tangohia te 2.4x mai i ngā taha e rua.
-0.6x=4.8
Pahekotia te 1.8x me -2.4x, ka -0.6x.
x=\frac{4.8}{-0.6}
Whakawehea ngā taha e rua ki te -0.6.
x=\frac{48}{-6}
Whakarohaina te \frac{4.8}{-0.6} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-8
Whakawehea te 48 ki te -6, kia riro ko -8.
