\(\sqrt{4x^2-12x+9}+3=2x\)

<=>\(\sqrt{4x^2-12x+9}=2x-3\)

<=>\(4x^2-12x+9=\left(2x-3\right)^2\)

<=>\(4x^2-12x+9=4x^2-12x+9\)

<=>\(4x^2-12x+9-4x^2+12x-9=0\)

<=>0=0( luôn đúng )

=> phương trình trên có vô số nghiệm

Vậy phương trình trên có vô số nghiệm

(25-(x+1,85)):3=7

<=>25-(x+1,85)=7.3

<=>25-x-1,85=21

<=>(25-1,85)-x=21

<=>23,75-x=21

<=>-x=21-23.75

<=>-x=-2,75

<=>x=2.75

Vậy x=2,75
