Kua tāruatia ki te papatopenga
4\left(x+3\right)=16x-24
Whakareatia ngā taha e rua o te whārite ki te 8.
4x+12=16x-24
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+3.
4x+12-16x=-24
Tangohia te 16x mai i ngā taha e rua.
-12x+12=-24
Pahekotia te 4x me -16x, ka -12x.
-12x=-24-12
Tangohia te 12 mai i ngā taha e rua.
-12x=-36
Tangohia te 12 i te -24, ka -36.
x=\frac{-36}{-12}
Whakawehea ngā taha e rua ki te -12.
x=3
Whakawehea te -36 ki te -12, kia riro ko 3.
