Answer 1

$\displaystyle\bf\\\frac{5x-1}{6} +\frac{2x-7}{9} =\frac{x-3}{2} \\\\\\\frac{5x-1}{6} \cdot 18+\frac{2x-7}{9} \cdot 18=\frac{x-3}{2} \cdot 18\\\\\\(5x-1)\cdot 3+(2x-7)\cdot 2=(x-3)\cdot 9\\\\15x-3+4x-14=9x-27\\\\19x-17=9x-27\\\\19x-9x=-27+17\\\\10x=-10\\\\\boxed{x=-1}$

Answer 2

Ответ:

х = -1

Объяснение:

5х - 1/6 + 2х - 7/9 = х - 3/2

3(5х - 1) + 2 (2х - 7) = 9 (х - 3)

15х - 3 + 4х - 14 = 9х - 27

19х - 17 =9х - 17

19х - 9х = - 27 + 17

10х = - 10

х = -1
