Solving this problem entails of simplifying the given expression. To do this we will first combine like terms. This step is taken to gather the terms in the expression that correspond with each other. Because the terms 'x' and '7x' both contain the same variable, we will combine these. Because the terms '5' and '11' are both numeral digits, we will combine these as well.
x + 5 + 7x + 11
(x + 7x) + (5 + 11)
The like terms have now been grouped together.
The final step is to add each of the common terms together in order to get the expression in its simplest form.
(x + 7x) + (5 + 11)
8x + 16
The expression has been simplified. The correct answer should be a. 8x + 16
