Answer:
13
Step-by-step explanation:
Simplify 8 - {x - (5 + x)}
We need to simplify 8-(x- (5+x))
To simplify it we need to use order of operation
Order of operation is PEMDAS
Parenthesis , exponents , multiply , divide , add and subtract
So first we start with parenthesis
\(8-(x- (5+x))\)
multiply negative sign inside the parenthesis
\(8-(x-5-x)\)
combine like terms x-x becomes 0
\(8-(-5))\)
\(8+5\)
