5 raruraru e ōrite ana ki:
\frac { x } { 16 } + \frac { ( 140 - x ) } { 6 } = 15
Tohaina
Kua tāruatia ki te papatopenga
3x+8\left(140-x\right)=720
Me whakarea ngā taha e rua o te whārite ki te 48, arā, te tauraro pātahi he tino iti rawa te kitea o 16,6.
3x+1120-8x=720
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 140-x.
-5x+1120=720
Pahekotia te 3x me -8x, ka -5x.
-5x=720-1120
Tangohia te 1120 mai i ngā taha e rua.
-5x=-400
Tangohia te 1120 i te 720, ka -400.
x=\frac{-400}{-5}
Whakawehea ngā taha e rua ki te -5.
x=80
Whakawehea te -400 ki te -5, kia riro ko 80.
