Rezolvati in R ecuatia :

x+2 supra 3 - 5 supra 7 = 3*x-6 supra 7 + 1 supra 3



Răspuns :

Bser
(x+2-1)/3=(3x-6+5)/7 => 7(x+1)=3(3x-1) => 7x+7=9x-3=> 9x-7x=7+3 => 2x=10 => x=5

x+2 supra 3 -5 supra 7=3x-6 supra 7 +1 supra 3
Impartim ecuatia cu 21
Obtinem :
7x+14-15=9x-18+7 <=>7x-1=9x-11 <=> -2x= -10 | :(-2) <=>x = +5
x= +5
