Question

Rezolvati ecuatia:
$\frac{1}{4}$·{$\frac{1}{4}$·[$\frac{1}{4}$·($\frac{1}{4}$·x+1)+4]+1}+4=5

Answer 1

1/4·{1/4·[1/4·(1/4·x+1)+4]+1}+4=5

1/4·{1/4·[1/4·(1/4·x+1)+4]+1}+4=5

1/4·{1/4·[1/4·(x/4+1)+4]+1}+4=5

1/4·{1/4·[1/4·(x+4)/4+4]+1}+4=5

1/4·[((x+4)/16+4)+1]+4=5

1/4·[(x+4+16·4)/16+1]+4=5

1/4·[(x+4+64+16)/16]=5 - 4

1/4·(x+84)/16=1

(x+84)/16·4=1

x+84=16·4

x=64-84

x=-20
