Answer: [tex]\bold{\dfrac{2(a-5)}{3a-5}}[/tex]
Step-by-step explanation:
You can't actually "solve" this because there is no equation. But you can simplify the expression.
[tex]\dfrac{a+11}{3a-5}+\dfrac{a-21}{3a-5}\\\\\text{Since they already have the same denominator, we can add the numerators:}\\\dfrac{a+11+a-21}{3a-5}=\dfrac{2a-10}{3a-5}=\dfrac{2(a-5)}{3a-5}\\\\\text{Since there are no common factors to cancel out, this is simplified.}[/tex]
