Question

VA ROG AJUTATI-MA cu b) ; d) ; e) din poza .

Answer 1

(2x-1)/(2x+1)=(5x-3)/(5x+3)
(2x-1)(5x+3)=(5x-3)(2x+1)
10x²-5x+6x-3=10x²-6x+5x-3
-5x+6x=-6x+5x
x=-x
2x=0
x=0


2+(3x-1)/(x-2)=(x+10)/(x-2)+x/(2-x)
2+(3x-1)/(x-2)=(x+10)/(x-2)-x/(x-2)
2x-4+3x-1=x+10-x
5x-5=10
5x=15
x=3


[2x+5-3(x+2)]/(3-2x)=2(x+1)/(4x+5)
(2x+5-3x-6)/(3-2x)=2(x+1)/(4x+5)
(x+1)/(2x-3)=2(x+1)/(4x+5)
4x²+5x+4x+5=4x²-6x+4x-6
9x+5=-2x-6
11x=-11
x=-1
