Remember PEMDAS - Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction - this is the order of operations. First, you must distribute 5(x+2), that would be 5x+10. Then rewrite: -3x+5x+10. Finally, simplify.
Simplified: 2x+10
This is your answer
Not sure how the other person got 2x+2...
Hope that helps!
