Answer:
Our answer is [tex]x=-2+\sqrt{2}[/tex].
Step-by-step explanation:
To solve for x, we need to isolate the variable. We can do so by subtracting 2 to both sides.
[tex]x+2=\sqrt{2} \\x+2-2=-2+\sqrt{2} \\\\x=-2+\sqrt{2} \\[/tex]
Our answer is [tex]x=-2+\sqrt{2}[/tex].
To find the decimal, calculate with a calculator.
