0.65x-0.65=0.37\left(x+1\right)+0.1
Whakamahia te āhuatanga tohatoha hei whakarea te 0.65 ki te x-1.
0.65x-0.65=0.37x+0.37+0.1
Whakamahia te āhuatanga tohatoha hei whakarea te 0.37 ki te x+1.
0.65x-0.65=0.37x+0.47
Tāpirihia te 0.37 ki te 0.1, ka 0.47.
0.65x-0.65-0.37x=0.47
Tangohia te 0.37x mai i ngā taha e rua.
0.28x-0.65=0.47
Pahekotia te 0.65x me -0.37x, ka 0.28x.
0.28x=0.47+0.65
Me tāpiri te 0.65 ki ngā taha e rua.
0.28x=1.12
Tāpirihia te 0.47 ki te 0.65, ka 1.12.
x=\frac{1.12}{0.28}
Whakawehea ngā taha e rua ki te 0.28.
x=\frac{112}{28}
Whakarohaina te \frac{1.12}{0.28} mā te whakarea i te taurunga me te tauraro ki te 100.
x=4
Whakawehea te 112 ki te 28, kia riro ko 4.
