Odpowiedź:
[tex]8-\frac{-2x+3}{4}=\frac{5-x}{3}-7\ \ /*12\\\\96-3(-2x+3)=4(5-x)-84\\\\96+6x-9=20-4x-84\\\\87+6x=-64-4x\\\\6x+4x=-64-87\\\\10x=-151\ \ /:10\\\\x=-\frac{151}{10}\\\\x=-15\frac{1}{10}[/tex]
8 - (-2x + 3)/4 = (5 - x)/3 - 7
8 + 1/2x - 3/4 = 5/3 - 1/3x - 7
1/2x + 1/3x = 1 2/3 - 7 - 7 1/4
3/6x + 2/6x = 1 8/12 - 14 3/12
5/6x = 1 8/12 - 13 15/12 /*6/5
x = -12 7/12 * 6/5 = -151/12 * 6/5 = -151/10 = -15,1
