It looks like there is a mistake in the equation you provided. You have two equals signs, which suggests there might be two separate equations, or something got mixed up.

If it's meant to be two separate equations, they might be:

1. \( 20 - (x + 14) = 520 \)
2. \( 5 - (x + 14) = 5 \)

Let's solve them individually:

1. \( 20 - (x + 14) = 520 \)

Simplify inside the parentheses:

\( 20 - x - 14 = 520 \)

Simplify further:

\( 6 - x = 520 \)

Subtract 6 from both sides:

\( -x = 514 \)

Divide by -1:

\( x = -514 \)

2. \( 5 - (x + 14) = 5 \)

Simplify inside the parentheses:

\( 5 - x - 14 = 5 \)

Simplify further:

\( -x - 9 = 5 \)

Add 9 to both sides:

\( -x = 14 \)

Divide by -1:

\( x = -14 \)

So, if those were meant to be two separate equations, \( x = -514 \) for the first equation and \( x = -14 \) for the second equation. If the equations are meant to be interpreted differently, please provide clarification.
