Mathematics

This problem is tough until you clean it up so you can see what's going on.

On the left side, (7 + 5 - 3) = 9 .  So the left side is  x + 9 .

On the right side,  (16 - 8) = 8.

So the equation is really          <u>x + 9 = 8</u>

Subtract 9 from each side:     <em> x      = -1</em>

7+x+5-3=16-8  \\  \\ 7 + x + - 5 - 3 = 16 + - 8  \\  \\ (x) + (7 + 5 + - 3 ) = ( 16 + - 8 )  \\  \\ x + 9 = 8  \\  \\ x + 9 - 9 = 8 - 9  \\  \\ \huge{\boxed{ x = -1}}
