Question

2/5у+4/5у-2=5/1/3
4/3у-2/3у-3=2/1/2

Answer 1

$frac{2}{5}y + frac{4}{5} y - 2 = 5 frac{1}{3} \ frac{6}{5}y = 5 frac{1}{3} + 2 \ 1 frac{1}{5} y = 7 frac{1}{3} \ y = 7 frac{1}{3} div 1 frac{1}{5} \ y = frac{22 times 5}{3 times 6} \ y = frac{55}{9} = 6 frac{1}{9} \ \ frac{4}{3} y - frac{2}{3} y - 3 = 2 frac{1}{2} \ frac{2}{3} y = 2 frac{1}{2} + 3 \ frac{2}{3} y = 5 frac{1}{2} \ y = 5 frac{1}{2} div frac{2}{3} \ y = frac{11 times 3}{2 times 2} \ y = frac{33}{4} = 8 frac{1}{4}$
