\left(4+x\right)\left(5-0x\right)=24
Whakareatia te 0 ki te 5, ka 0.
\left(4+x\right)\left(5-0\right)=24
Ko te tau i whakarea ki te kore ka hua ko te kore.
\left(4+x\right)\times 5=24
Tangohia te 0 i te 5, ka 5.
20+5x=24
Whakamahia te āhuatanga tohatoha hei whakarea te 4+x ki te 5.
5x=24-20
Tangohia te 20 mai i ngā taha e rua.
5x=4
Tangohia te 20 i te 24, ka 4.
x=\frac{4}{5}
Whakawehea ngā taha e rua ki te 5.
