Answer:
3x+8
Explanation:
First, we can write the sum into a mathematical expression:
The sum of (x+5) and (2x+3)
(x+5)+(2x+3)
However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:
x+5+2x+3
Using commutative property, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:
x+2x+5+3
Now we can simplify the expression:
3x+8
