Question

this problem is under linear equations, 2 square root of x+3 = 7. Need help?

Answer 1

Try squaring both sides.

Answer 2

\( \color{Black}{\Rightarrow \sqrt{x + 3}^2 = 7^2}\)

Answer 3

You will get \(x + 3 = 49\), now subtract 3 from both sides.

Answer 4

\[2\sqrt{x+3} = 7\]
square both sides
\[(2\sqrt{x+3})^2 = 7^2\]
\[4(x+3) = 49\]
can you do it now? or do you need more help?
