Kua tāruatia ki te papatopenga
4\left(2+x\right)=22\times 2
Me whakarea ngā taha e rua ki te 2.
8+4x=22\times 2
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2+x.
8+4x=44
Whakareatia te 22 ki te 2, ka 44.
4x=44-8
Tangohia te 8 mai i ngā taha e rua.
4x=36
Tangohia te 8 i te 44, ka 36.
x=\frac{36}{4}
Whakawehea ngā taha e rua ki te 4.
x=9
Whakawehea te 36 ki te 4, kia riro ko 9.
