How do you add or subtract #(3/x) + (13)/(x – 11)#?

By treating this expression same as normal fraction adding and subtracting:

To add or subtract fractions, you need a common denominator. In this case, the common denominator is (x)(x - 11). To add the fractions, you would multiply the numerator of the first fraction (3) by (x - 11) and the numerator of the second fraction (13) by x. Then, you add the two resulting numerators and place the sum over the common denominator. To subtract the fractions, you follow the same steps but subtract the second numerator from the first numerator instead of adding them.

To add or subtract the fractions ( \frac{3}{x} ) and ( \frac{13}{x-11} ), you first need to find a common denominator, which is ( x(x-11) ). Then, you can rewrite each fraction with this common denominator and proceed with the addition or subtraction. After combining the fractions, simplify if possible. The result will be a single fraction.
