Kua tāruatia ki te papatopenga
4\times 3x=5\left(x-2\right)
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 5,4.
12x=5\left(x-2\right)
Whakareatia te 4 ki te 3, ka 12.
12x=5x-10
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-2.
12x-5x=-10
Tangohia te 5x mai i ngā taha e rua.
7x=-10
Pahekotia te 12x me -5x, ka 7x.
x=\frac{-10}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{10}{7}
Ka taea te hautanga \frac{-10}{7} te tuhi anō ko -\frac{10}{7} mā te tango i te tohu tōraro.
