Linear Equation
5 raruraru e ōrite ana ki:
\frac { 1 } { 8 } = \frac { 1 } { 4 } + \frac { 1 } { v }
Tohaina
Kua tāruatia ki te papatopenga
v=8v\times \frac{1}{4}+8
Tē taea kia ōrite te tāupe v ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 8v, arā, te tauraro pātahi he tino iti rawa te kitea o 8,4,v.
v=\frac{8}{4}v+8
Whakareatia te 8 ki te \frac{1}{4}, ka \frac{8}{4}.
v=2v+8
Whakawehea te 8 ki te 4, kia riro ko 2.
v-2v=8
Tangohia te 2v mai i ngā taha e rua.
-v=8
Pahekotia te v me -2v, ka -v.
v=-8
Me whakarea ngā taha e rua ki te -1.
