Question 947334
If the sum of the ages in eight years will be 76, the current sum is 76-16=60 (subtract eight years for each).
M=Michael's age; A=Amber's age=M-8
M+A=60 Substitute for A
M+(M-8)=60 Add 8 to each side
2M=68 Divide each side by 2
M=34 ANSWER: Michael is 34 years old
CHECK
A=M-8=26 years old Amber is 26 years old
In eight years, sum will be 76:
(M+8)+(A+8)=76
(34+8)+(26+8)=76
42+34=76
76=76
