Whakaoti mō c
c = \frac{163}{8} = 20\frac{3}{8} = 20.375
Tohaina
Kua tāruatia ki te papatopenga
171-9c=4\times 2-c
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 19-c.
171-9c=8-c
Whakareatia te 4 ki te 2, ka 8.
171-9c+c=8
Me tāpiri te c ki ngā taha e rua.
171-8c=8
Pahekotia te -9c me c, ka -8c.
-8c=8-171
Tangohia te 171 mai i ngā taha e rua.
-8c=-163
Tangohia te 171 i te 8, ka -163.
c=\frac{-163}{-8}
Whakawehea ngā taha e rua ki te -8.
c=\frac{163}{8}
Ka taea te hautanga \frac{-163}{-8} te whakamāmā ki te \frac{163}{8} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
