Question

rEZOLVATI ECUATIA; x(1 +1 supra3 +1 supra 5)= x(1 supra 2+1 supra 4+1 supra 6)+1 supra 4+1 supra 5+ 1 supra 6.

Answer 1

/=supra

=
x(15+5+3)/15=x(6+3+2)/12+(15+12+10)/60
23x/15=11x/12+37/60
n.c.=60
*=inmultire
4*23x=5*11x+37
92x=55x+37
92x-55x=37
37x=37
x=37:37
x=1

Answer 2

x(1+1/3+1/5) = x(1/2+1/4+1/6) + 1/4 + 1/ 5 +1/6
x(15/15+5/15+3/15) = x(6/12+3/12+2/12) + 15/60+ 12/60 + 10/60
x * 23/15 = x*11/12 + 37/60
x(23/15 - 11/12) = 37/60
x(92/60 - 55/60) = 37/60
x * 37/60 = 37/60
x = 37/60 : 37/60
x = 37/60 x 60/37
x = 1
