Kua tāruatia ki te papatopenga
3\left(x+4\right)=24x-8
Me whakarea ngā taha e rua o te whārite ki te 24, arā, te tauraro pātahi he tino iti rawa te kitea o 8,3.
3x+12=24x-8
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+4.
3x+12-24x=-8
Tangohia te 24x mai i ngā taha e rua.
-21x+12=-8
Pahekotia te 3x me -24x, ka -21x.
-21x=-8-12
Tangohia te 12 mai i ngā taha e rua.
-21x=-20
Tangohia te 12 i te -8, ka -20.
x=\frac{-20}{-21}
Whakawehea ngā taha e rua ki te -21.
x=\frac{20}{21}
Ka taea te hautanga \frac{-20}{-21} te whakamāmā ki te \frac{20}{21} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
