Kua tāruatia ki te papatopenga
24x=18\left(28-x\right)
Whakareatia te 2 ki te 12, ka 24.
24x=504-18x
Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te 28-x.
24x+18x=504
Me tāpiri te 18x ki ngā taha e rua.
42x=504
Pahekotia te 24x me 18x, ka 42x.
x=\frac{504}{42}
Whakawehea ngā taha e rua ki te 42.
x=12
Whakawehea te 504 ki te 42, kia riro ko 12.
