Question 421104
Mozart composed 11 less than of the number of symphonies that Haydn composed.
Together they compose 145 symphonies. How many symphonies did Mozart compose?
---------------------------------
Equations:
M + H = 145 symphonies
M = H + 11
--------------------
substitute for "M" and solved for "H":
H+11+H = 145
2H = 134
H = 67 (# composed by Haydn)
---
Solve for "M":
M = H+11
M = 67+11 = 68 (# composed by Mozart)
