Question

Rezolvati ecuatia :

{[(2x+3)*2 +3]*2+3}*2+3=85

Answer 1

{[(2x+3)*2 +3]*2+3}*2+3=85/-3 
{[(2x+3)*2 +3]*2+3}*2=82/:2 
[(2x+3)*2 +3]*2+3=41/-3
[(2x+3)*2 +3]*2=38/:2 
(2x+3)*2 +3=19/-3 
(2x+3)*2=16/:2 
2x+3=8/-3
2x=5
x=5/3
Sper ca te-am ajutat :* 

Answer 2

{[(2x+3)×2+3]×2+3}×2=85-3=82
[(2x+3)×2+3]×2+3=82÷2=41
(2x+3)×2=41-3=38
2x+3=38÷2=19
2x=19-3=16
x=16÷2=8
