5 raruraru e ōrite ana ki:
\frac { 3 ( x - 2 ) } { 5 } = x + \frac { 2 x } { 3 }
Tohaina
Kua tāruatia ki te papatopenga
3\times 3\left(x-2\right)=15x+5\times 2x
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 5,3.
9\left(x-2\right)=15x+5\times 2x
Whakareatia te 3 ki te 3, ka 9.
9x-18=15x+5\times 2x
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x-2.
9x-18=15x+10x
Whakareatia te 5 ki te 2, ka 10.
9x-18=25x
Pahekotia te 15x me 10x, ka 25x.
9x-18-25x=0
Tangohia te 25x mai i ngā taha e rua.
-16x-18=0
Pahekotia te 9x me -25x, ka -16x.
-16x=18
Me tāpiri te 18 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{18}{-16}
Whakawehea ngā taha e rua ki te -16.
x=-\frac{9}{8}
Whakahekea te hautanga \frac{18}{-16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
