Kua tāruatia ki te papatopenga
3\left(5.4+x\right)=7.2\times 6
Me whakarea ngā taha e rua ki te 6.
16.2+3x=7.2\times 6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5.4+x.
16.2+3x=43.2
Whakareatia te 7.2 ki te 6, ka 43.2.
3x=43.2-16.2
Tangohia te 16.2 mai i ngā taha e rua.
3x=27
Tangohia te 16.2 i te 43.2, ka 27.
x=\frac{27}{3}
Whakawehea ngā taha e rua ki te 3.
x=9
Whakawehea te 27 ki te 3, kia riro ko 9.
