\frac{65}{1000}x=\frac{8.5}{100}\left(2490-x\right)
Whakarohaina te \frac{6.5}{100} mā te whakarea i te taurunga me te tauraro ki te 10.
\frac{13}{200}x=\frac{8.5}{100}\left(2490-x\right)
Whakahekea te hautanga \frac{65}{1000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{13}{200}x=\frac{85}{1000}\left(2490-x\right)
Whakarohaina te \frac{8.5}{100} mā te whakarea i te taurunga me te tauraro ki te 10.
\frac{13}{200}x=\frac{17}{200}\left(2490-x\right)
Whakahekea te hautanga \frac{85}{1000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{13}{200}x=\frac{17}{200}\times 2490+\frac{17}{200}\left(-1\right)x
Whakamahia te āhuatanga tohatoha hei whakarea te \frac{17}{200} ki te 2490-x.
\frac{13}{200}x=\frac{17\times 2490}{200}+\frac{17}{200}\left(-1\right)x
Tuhia te \frac{17}{200}\times 2490 hei hautanga kotahi.
\frac{13}{200}x=\frac{42330}{200}+\frac{17}{200}\left(-1\right)x
Whakareatia te 17 ki te 2490, ka 42330.
\frac{13}{200}x=\frac{4233}{20}+\frac{17}{200}\left(-1\right)x
Whakahekea te hautanga \frac{42330}{200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
\frac{13}{200}x=\frac{4233}{20}-\frac{17}{200}x
Whakareatia te \frac{17}{200} ki te -1, ka -\frac{17}{200}.
\frac{13}{200}x+\frac{17}{200}x=\frac{4233}{20}
Me tāpiri te \frac{17}{200}x ki ngā taha e rua.
\frac{3}{20}x=\frac{4233}{20}
Pahekotia te \frac{13}{200}x me \frac{17}{200}x, ka \frac{3}{20}x.
x=\frac{4233}{20}\times \frac{20}{3}
Me whakarea ngā taha e rua ki te \frac{20}{3}, te tau utu o \frac{3}{20}.
x=\frac{4233\times 20}{20\times 3}
Me whakarea te \frac{4233}{20} ki te \frac{20}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{4233}{3}
Me whakakore tahi te 20 i te taurunga me te tauraro.
x=1411
Whakawehea te 4233 ki te 3, kia riro ko 1411.
