5 raruraru e ōrite ana ki:
= \frac { 2 x - 10 } { 20 } + \frac { 4 x + 5 } { 13 } = 6
Tohaina
Kua tāruatia ki te papatopenga
13\left(2x-10\right)+20\left(4x+5\right)=1560
Me whakarea ngā taha e rua o te whārite ki te 260, arā, te tauraro pātahi he tino iti rawa te kitea o 20,13.
26x-130+20\left(4x+5\right)=1560
Whakamahia te āhuatanga tohatoha hei whakarea te 13 ki te 2x-10.
26x-130+80x+100=1560
Whakamahia te āhuatanga tohatoha hei whakarea te 20 ki te 4x+5.
106x-130+100=1560
Pahekotia te 26x me 80x, ka 106x.
106x-30=1560
Tāpirihia te -130 ki te 100, ka -30.
106x=1560+30
Me tāpiri te 30 ki ngā taha e rua.
106x=1590
Tāpirihia te 1560 ki te 30, ka 1590.
x=\frac{1590}{106}
Whakawehea ngā taha e rua ki te 106.
x=15
Whakawehea te 1590 ki te 106, kia riro ko 15.
