Question

Verificat daca x=3
2x-1=5
3x-1=2x+2
x-1supra4=1supra2
x la puterea a 2 a=9
|x-5|=2
x supra radical din 3= radical din 3
2(x-1)=3x
-2x+5= -11
VA ROG ESTE URGENT

Answer 1

2x-1=5
2x=6
x=3 A
3x3-1=2x2+2
9-1=4+2
8=6 F
$x- \frac{1}{4} = \frac{1}{2} =\ \textgreater \ x= \frac{3}{4}$A
$3^{2} =9 A$
$|3-5|=2=\ \textgreater \ |-2|=2A$
3supra radical din 3=radical din 3A
2(3-1)=3x3
2x3=3x3
6=9 F
-2x3+5=-11
-8+5=-11
-3=-11F
