Question

2x+1:3-7x+5:15=x-2:5

Answer 1

$2x+1:3-7x+5:15=x-2:5\ 2x+frac{1}{3}-7x+frac{5}{15}=x-0.4\ \ -5x+frac{1}{3}+frac{5}{15}=x-0.4\ \-5x+frac{2}{3}=x-0.4\ \  -5x-x+frac{2}{3}=-0.4 \ \-5x-x=-0.4-frac{2}{3}\ \ -6x=-0.4-frac{2}{3} \ \ -6x=-frac{2}{5}-frac{2}{3}  \ \ -frac{6+10}{15} \ \ --6x=frac{16}{15} :-6\ \ x=frac{8}{45}$
