Kua tāruatia ki te papatopenga
4\left(x-3\right)=16
Me whakarea ngā taha e rua o te whārite ki te 28, arā, te tauraro pātahi he tino iti rawa te kitea o 7,28.
4x-12=16
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-3.
4x=16+12
Me tāpiri te 12 ki ngā taha e rua.
4x=28
Tāpirihia te 16 ki te 12, ka 28.
x=\frac{28}{4}
Whakawehea ngā taha e rua ki te 4.
x=7
Whakawehea te 28 ki te 4, kia riro ko 7.
