Question

2*(25х+1)+3 13=4- 12*(45х-1) Пожалуйста,решите!!

Answer 1

2*(25х+1)+3 13=4- 12*(45х-1) 
4/5х+2+3 1/3 = 4- 2/5х+1/2
4/5х+ 2/5х =  4+1/2-2-3 1/3
6/5х= 5/2-10/3
6/5х=(15-20)/6
6/5х=-5/6
х=-1

Answer 2

$2*( frac{2}{5}x+1)+3 frac{1}{3}=4- frac{1}{2}*( frac{4}{5}x-1)$
$frac{4}{5}x+2+frac{10}{3}=4-frac{2}{5}x+frac{1}{2}$
$frac{4}{5}x+frac{2}{5}x=4+frac{1}{2}-2-frac{10}{3}$
$frac{6}{5}x=2+frac{1}{2}-frac{10}{3}$
$frac{6}{5}x= frac{12}{6}+frac{3}{6}-frac{20}{6}$
$frac{6}{5}x=-frac{5}{6}$
$x=-frac{5}{6}*frac{5}{6}$
$x=-frac{25}{36}$
