Subtracting fractions? (answer)

Since both denominators are 2 we only need to figure out (5x+8) - (5x-8). 5x - 5x is 0. 8 - -8 is the same as 8 + 8 so it is 16. 16 is our numerator. We need to put it with the denominator that is 2. 16 /2 reduces to 8. We can check this by replacing x with 2. (5*2+8)...

It looks like your answer is upside-down. 7/8/(-3) is the same thing as 7/8 รท -3/1. Now we have two fractions. To divide two fractions you flip the second one over so you change -3/1 into -1/3 and multiply. 7/8 x -1/3 = -7/24
