Answer 1

$(1\frac{7}{8}x-2\frac{1}{3})*24=4\\1\frac{7}{8}x-2\frac{1}{3}=4:24\\1\frac{7}{8}x=\frac{1}{6}+2\frac{1}{3} \\\frac{15}{8}x=\frac{1}{6}+\frac{14}{6}\\\frac{15}{8}x=\frac{15}{6} \\x=\frac{5}{2}:\frac{15}{8} \\ x=\frac{4}{3}=1\frac{1}{3}$

$4\frac{1}{12}-1\frac{5}{6}x=2 \frac{17}{24} \\-\frac{11}{6}x=2\frac{17}{24}-4\frac{2}{24} \\-\frac{11}{6}x=-1\frac{9}{24}\\x=\frac{33}{24}:\frac{11}{6} \\ x=\frac{3}{4}=0,75$
