Kua tāruatia ki te papatopenga
3\left(x-5\right)=4\left(2x-1\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3.
3x-15=4\left(2x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-5.
3x-15=8x-4
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x-1.
3x-15-8x=-4
Tangohia te 8x mai i ngā taha e rua.
-5x-15=-4
Pahekotia te 3x me -8x, ka -5x.
-5x=-4+15
Me tāpiri te 15 ki ngā taha e rua.
-5x=11
Tāpirihia te -4 ki te 15, ka 11.
x=\frac{11}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-\frac{11}{5}
Ka taea te hautanga \frac{11}{-5} te tuhi anō ko -\frac{11}{5} mā te tango i te tohu tōraro.
