0.12x-0.6-2.3=0.5\left(2x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 0.12 ki te x-5.
0.12x-2.9=0.5\left(2x+3\right)
Tangohia te 2.3 i te -0.6, ka -2.9.
0.12x-2.9=x+1.5
Whakamahia te āhuatanga tohatoha hei whakarea te 0.5 ki te 2x+3.
0.12x-2.9-x=1.5
Tangohia te x mai i ngā taha e rua.
-0.88x-2.9=1.5
Pahekotia te 0.12x me -x, ka -0.88x.
-0.88x=1.5+2.9
Me tāpiri te 2.9 ki ngā taha e rua.
-0.88x=4.4
Tāpirihia te 1.5 ki te 2.9, ka 4.4.
x=\frac{4.4}{-0.88}
Whakawehea ngā taha e rua ki te -0.88.
x=\frac{440}{-88}
Whakarohaina te \frac{4.4}{-0.88} mā te whakarea i te taurunga me te tauraro ki te 100.
x=-5
Whakawehea te 440 ki te -88, kia riro ko -5.
