You can put this solution on YOUR website!
M = Michael Jordan's age in 2011
L = Lebron James' age in 2011
.
M = 2L -9
.
M+L = 72
so
M = 72-L
.
substitute
.
72-L = 2L -9
-3L = -81
L = 27
.
M = 72-27
M = 45
.
Always check your work.
Is M = 2*L -9?
2L = 2*27 =54
54 -9 =45
Yes.
.
Answer: In 2011 Michael was 45 years old, and Lebron was 27 years old.
