What is the least common denominator for -3/x -6/8x^2

Assuming your second fraction is -6/(8x^2), the denominator of the second fraction already includes the first denominator as a factor, so it is the lowest common denominator.

The Least Common Denominator is 8x^2 for the fractions as written.


You can reduce the second fraction to -3/(4x^2), which would make the Least Common Denominator be 4x^2.

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
