Question

2 2/3:x+1/3=1 1/2:x-1 1/8

Answer 1

$2 frac{2}{3} div x + frac{1}{3} = 1.5 div x - 1 frac{1}{8}$
$frac{2 frac{2}{3} }{x} - frac{1.5}{x} = - 1 frac{3}{24} - frac{8}{24} = - 1 frac{11}{24} \ frac{ 2frac{20}{30} }{x} - frac{1 frac{15}{30} }{x} = - 1 frac{11}{24} \ frac{1 frac{1}{6} }{x} = - 1 frac{11}{24} \ x = - frac{7}{6} times frac{24}{35} \ x = - frac{4}{5} \ x = - 0.8$

Answer 2

8/3*1/x+1/3=3/2*1/x-9/8
8/3x+1/3=3/2x-9/8
8/3x-3/2x=-9/8-1/3
7/6x=-35/24
168=-210x
-210x=168
x=-0,8
