Question

What is the solution of StartRoot 2 x + 4 EndRoot = 16?

Answer 1

x=126

Explanation:

Answer 2

We start with

`√(2x+4)=16`

Since both sides of the equality are positive, we can square them to get

`2x+4=256`

Subtract 4 from both sides and then divide both sides by 2:

`2x+4=256 \iff 2x=252\iff x=126`
