Solve a+11/3a-5+a-21/3a-5

Mathematics
1 answer:
sineoko [7]3 years ago
8 0

Answer:   \bold{\dfrac{2(a-5)}{3a-5}}

<u>Step-by-step explanation:</u>

You can't actually "solve" this because there is no equation.  But you can simplify the expression.

\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.}
