Zadanie 1

[tex]1-\dfrac{3x-88}{7}=5x\ \mid\cdot7\\\\7-(3x-88)=35x\\\\7-3x+88=35x\\\\38x=95\\\\\boxed{x=2,5}[/tex]

Zadanie 2

[tex]-\dfrac{x}{2}=3x-\dfrac{3+2x}{4}\ \mid\cdot4\\\\-2x=12x-(3+2x)\\\\-2x=12x-3-2x\\\\-2x=10x-3\\\\12x=3\\\\\boxed{x=\dfrac{1}{4}}[/tex]

Zadanie 3

[tex]3-\dfrac{3x}{2}=\dfrac{5}{8}-\dfrac{4x-3}{6}\ \mid\cdot24\\\\72-36x=15-4(4x-3)\\\\72-36x=15-16x+12\\\\72-36x=27-16x\\\\20x=45\\\\\boxed{x=2,25}[/tex]

Zadanie 4

[tex]\dfrac{3-2x}{5}+8=\dfrac{5x+2}{2}-x\ \mid\cdot10\\\\2(3-2x)+80=5(5x+2)-10x\\\\6-4x+80=25x+10-10x\\\\86-4x=15x+10\\\\19x=76\\\\\boxed{x=4}[/tex]
