Felicia played video games for (4x+3) + 115-x2=?

Your answer is 2x+118. Here is how I got it.

So we need to simplify the problem by first removing the parenthesis to get this

4x+3+115-2x

Now we need to add the numbers 3+115=118 to get this

4x-2x+118

Then we combine like 4x-2x=2x to get this

2x+118

So your final answer is 2x+188 because we cant go any further to simplify the expression.
