Kua tāruatia ki te papatopenga
3\left(3-x\right)=2\left(5+2x\right)
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 6x, arā, te tauraro pātahi he tino iti rawa te kitea o 2x,3x.
9-3x=2\left(5+2x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3-x.
9-3x=10+4x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 5+2x.
9-3x-4x=10
Tangohia te 4x mai i ngā taha e rua.
9-7x=10
Pahekotia te -3x me -4x, ka -7x.
-7x=10-9
Tangohia te 9 mai i ngā taha e rua.
-7x=1
Tangohia te 9 i te 10, ka 1.
x=\frac{1}{-7}
Whakawehea ngā taha e rua ki te -7.
x=-\frac{1}{7}
Ka taea te hautanga \frac{1}{-7} te tuhi anō ko -\frac{1}{7} mā te tango i te tohu tōraro.
