Tohaina
Kua tāruatia ki te papatopenga
7\left(v+5\right)=-5
Tē taea kia ōrite te tāupe v ki -5 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te v+5.
7v+35=-5
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te v+5.
7v=-5-35
Tangohia te 35 mai i ngā taha e rua.
7v=-40
Tangohia te 35 i te -5, ka -40.
v=\frac{-40}{7}
Whakawehea ngā taha e rua ki te 7.
v=-\frac{40}{7}
Ka taea te hautanga \frac{-40}{7} te tuhi anō ko -\frac{40}{7} mā te tango i te tohu tōraro.
