3\left(x-3\right)=2\left(x-3\right)\times 6-2\left(x+10\right)
Tē taea kia ōrite te tāupe x ki 3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x-3\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2,x-3.
3x-9=2\left(x-3\right)\times 6-2\left(x+10\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
3x-9=12\left(x-3\right)-2\left(x+10\right)
Whakareatia te 2 ki te 6, ka 12.
3x-9=12x-36-2\left(x+10\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te x-3.
3x-9=12x-36-2x-20
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+10.
3x-9=10x-36-20
Pahekotia te 12x me -2x, ka 10x.
3x-9=10x-56
Tangohia te 20 i te -36, ka -56.
3x-9-10x=-56
Tangohia te 10x mai i ngā taha e rua.
-7x-9=-56
Pahekotia te 3x me -10x, ka -7x.
-7x=-56+9
Me tāpiri te 9 ki ngā taha e rua.
-7x=-47
Tāpirihia te -56 ki te 9, ka -47.
x=\frac{-47}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{47}{7}
Ka taea te hautanga \frac{-47}{-7} te whakamāmā ki te \frac{47}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
