Kua tāruatia ki te papatopenga
4\times 2x-2\left(2x+1\right)=3\left(3x-5\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6,4.
8x-2\left(2x+1\right)=3\left(3x-5\right)
Whakareatia te 4 ki te 2, ka 8.
8x-4x-2=3\left(3x-5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 2x+1.
4x-2=3\left(3x-5\right)
Pahekotia te 8x me -4x, ka 4x.
4x-2=9x-15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3x-5.
4x-2-9x=-15
Tangohia te 9x mai i ngā taha e rua.
-5x-2=-15
Pahekotia te 4x me -9x, ka -5x.
-5x=-15+2
Me tāpiri te 2 ki ngā taha e rua.
-5x=-13
Tāpirihia te -15 ki te 2, ka -13.
x=\frac{-13}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{13}{5}
Ka taea te hautanga \frac{-13}{-5} te whakamāmā ki te \frac{13}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
