5 raruraru e ōrite ana ki:
\frac { 11 x - 3 x } { 2 } = \frac { 4 + 2 x } { 3 }
Tohaina
Kua tāruatia ki te papatopenga
3\left(11x-3x\right)=2\left(4+2x\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
3\times 8x=2\left(4+2x\right)
Pahekotia te 11x me -3x, ka 8x.
24x=2\left(4+2x\right)
Whakareatia te 3 ki te 8, ka 24.
24x=8+4x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4+2x.
24x-4x=8
Tangohia te 4x mai i ngā taha e rua.
20x=8
Pahekotia te 24x me -4x, ka 20x.
x=\frac{8}{20}
Whakawehea ngā taha e rua ki te 20.
x=\frac{2}{5}
Whakahekea te hautanga \frac{8}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
