Kua tāruatia ki te papatopenga
-4x=-35
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 5,4.
x=\frac{-35}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{35}{4}
Ka taea te hautanga \frac{-35}{-4} te whakamāmā ki te \frac{35}{4} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
