you cannot add a and 8. you can multiply them to get 8a. but a variable and number cannot add

To solve this you have to set up a proportion. 5.2/8=x/100 Then you cross multiply to get 520=8x. Then you divide by 8 to attain an answer of 65, or 65%.
You can do this by finding two numbers that add to make 18 (the coefficient of the middle term) and multiply to make 65 (the product of the first term's coefficient and the last term). As it happens, 65 only has two factors, 5 and 13, which do add up to make 18. Unfortunately, they won't work for this equation, as we need them to add up to 18, and multiply to make negative 65. So this statement can not be factored.
