Question

Rezolvatii ecuatiile:
4-2,3x=-0,6
$\sqrt{2}$ + 2x=sqrt{18} [/tex]

Answer 1

$4-2,3x=-0,6 \\ -2,3x=-0,6-4 \\ 2,3x=0,6+4 \\ 2,3x=4,6 \Rightarrow \boxed{x=2}.$

$\sqrt{2} +2x= \sqrt{18} \\ 2x= \sqrt{18} - \sqrt{2} \\ 2x=3 \sqrt{2}- \sqrt{2} \\ 2x=2 \sqrt{2} \Rightarrow \boxed{x= \sqrt{2}}.$
