Question

розв'язати рівняння : 3/3(1/3x-1/2)=6x-2(x-1 1/4)
​

Answer 1

$\frac{3}{3} ( \frac{1}{3} x - \frac{1}{2} ) = 6x - 2(x - 1 \frac{1}{4} \\ 1( \frac{1}{3} x - \frac{1}{2} ) = 6x - 2(x - \frac{5}{4} ) \\ \frac{1}{3} x - \frac{1}{2} = 6x - 2x + \frac{5}{2} \\ \frac{1}{3} x - \frac{1}{2} = 4x + \frac{5}{2} \\ 2x - 3 = 24x + 15 \\ 2x - 24x = 15 + 3 \\ - 22x = 18 \\ x = - \frac{9}{11}$
