Solve using the addition and multiplication principles: 13/5a + 9/4 = 37/8 13/5a + 9/4 - 9/4 = 37/8 - 9/4 13/5a = 28/4 5/13 * 13/5a = 28/4 a = 28/4 * 5/13 a = 140/52 Please let me know if I'm doing this right. Thank you!

Method is correct, but you need to have a common denominator when adding or subtracting fractions. So instead of $\displaystyle \frac{37}{8}-\frac{9}{4}$ it should be $\displaystyle \frac{37}{8}-\frac{18}{8}$

Thank you! you did not subtract $\displaystyle \frac{37}{8}-\frac{9}{4}$ correctly the correct answer is $\displaystyle \frac{19}{8}$ try reworking the problem with this information
So it would be 13/5a = 37/8 - 18/8 5/13 * 13/5a = 19/8 then a = 19/8 * 5/13 a = 95/104 OR I am just out of this world! Let me know if I got it right, please!
THat's correct
Can I simplify it any further?
THANK YOU TWO VERY MUCH! *****
