0.05x+90-0.06x=83.5
Whakamahia te āhuatanga tohatoha hei whakarea te 0.06 ki te 1500-x.
-0.01x+90=83.5
Pahekotia te 0.05x me -0.06x, ka -0.01x.
-0.01x=83.5-90
Tangohia te 90 mai i ngā taha e rua.
-0.01x=-6.5
Tangohia te 90 i te 83.5, ka -6.5.
x=\frac{-6.5}{-0.01}
Whakawehea ngā taha e rua ki te -0.01.
x=\frac{-650}{-1}
Whakarohaina te \frac{-6.5}{-0.01} mā te whakarea i te taurunga me te tauraro ki te 100.
x=650
Ka taea te hautanga \frac{-650}{-1} te whakamāmā ki te 650 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
