Question

dererminati cifra x stiind ca x,(34)+3,(4x)+4,(x3) = x + 8 !!!

Answer 1

x,(34)+3,(4x)+4,(x3) = x + 8
x,(34)=(100x+34-x)/99=(99x+34)/99
3,(4x)=(340+x-3)/99=(337+x)/99
4,(x3)=(400+10x+3-4)/99=(399+10x)/99

(99x+34)/99+(337+x)/99+(399+10x)/99=x+8
99x+34+337+x+399+10x=99x+792
11x+770=792
11x=22
x=2
