Question

Micheal is 4 times as old as Brandon and is also 27 years older than Brandon. It wants me to write a system of equations that represents this situation and solve. How do I do that?

Answer 1

M = 4b
m = b + 27

4b = b + 27
4b - b = 27
3b = 27
b = 27/3
b = 9......Brandon is 9

m = 4b
m = 4(9)
m = 36.....Michael is 36
