Tohaina
Kua tāruatia ki te papatopenga
4x+12=6\left(x-2\right)
Whakaarohia te whārite tuatahi. Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+3.
4x+12=6x-12
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x-2.
4x+12-6x=-12
Tangohia te 6x mai i ngā taha e rua.
-2x+12=-12
Pahekotia te 4x me -6x, ka -2x.
-2x=-12-12
Tangohia te 12 mai i ngā taha e rua.
-2x=-24
Tangohia te 12 i te -12, ka -24.
x=\frac{-24}{-2}
Whakawehea ngā taha e rua ki te -2.
x=12
Whakawehea te -24 ki te -2, kia riro ko 12.
x=12 y=3 z=3 a=3
Kua oti te pūnaha te whakatau.
