30x=(12-x)90
Tohaina
Kua tāruatia ki te papatopenga
30x=1080-90x
Whakamahia te āhuatanga tohatoha hei whakarea te 12-x ki te 90.
30x+90x=1080
Me tāpiri te 90x ki ngā taha e rua.
120x=1080
Pahekotia te 30x me 90x, ka 120x.
x=\frac{1080}{120}
Whakawehea ngā taha e rua ki te 120.
x=9
Whakawehea te 1080 ki te 120, kia riro ko 9.
