Answer:
Michael is 36 years old
Explanation:
Let M represent Michael's age, and let B represent Brandon's age,
"Michael is 4 times as old as Brandon" becomes
M = 4B
"Michael is also 27 years older than Brandon" becomes
M = B + 27
Since the two equations are equal to M, they are equal to each other, so we have...
4B = B + 27 now solve for B...
3B = 27
B = 9
There fore
M = 9 + 27 = 36
