0.06x+0.3=0.4\left(0.5x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 0.3 ki te 0.2x+1.
0.06x+0.3=0.2x-0.4
Whakamahia te āhuatanga tohatoha hei whakarea te 0.4 ki te 0.5x-1.
0.06x+0.3-0.2x=-0.4
Tangohia te 0.2x mai i ngā taha e rua.
-0.14x+0.3=-0.4
Pahekotia te 0.06x me -0.2x, ka -0.14x.
-0.14x=-0.4-0.3
Tangohia te 0.3 mai i ngā taha e rua.
-0.14x=-0.7
Tangohia te 0.3 i te -0.4, ka -0.7.
x=\frac{-0.7}{-0.14}
Whakawehea ngā taha e rua ki te -0.14.
x=\frac{-70}{-14}
Whakarohaina te \frac{-0.7}{-0.14} mā te whakarea i te taurunga me te tauraro ki te 100.
x=5
Whakawehea te -70 ki te -14, kia riro ko 5.
