First you have to make your denumenator equal find the least common multiple between the two. Then multiply the numerator with the same number you multiplied the denumerater. Then it's a simple mater of addition or subtraction.

I'd add them just as they are, and later convert the result into a mixed number.

7 times a number is 18 less than the square of that number. Find the positive solution.

Arte-miy333 [17]

So 7 x = x2 -18 so you get the quadratic x^2 -7x -18 and then get 2 x -9= -18 and 2 + -9 = -7 so you get (x + 2) ( x - 9) so the positive solution would be x-9 = 0 so x= 9. Hope this helps :)
