Kua tāruatia ki te papatopenga
3\left(54+x\right)=72\times 6
Me whakarea ngā taha e rua ki te 6.
162+3x=72\times 6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 54+x.
162+3x=432
Whakareatia te 72 ki te 6, ka 432.
3x=432-162
Tangohia te 162 mai i ngā taha e rua.
3x=270
Tangohia te 162 i te 432, ka 270.
x=\frac{270}{3}
Whakawehea ngā taha e rua ki te 3.
x=90
Whakawehea te 270 ki te 3, kia riro ko 90.
