K=Kevin's age; C=Christopher's age
K=2C
K-24=8(C-24)
K-24=8C-192 Add 192 to each side
K+168=8C Substitute for K, solve for C
2C+168=8C Subtract 2c from each side
168=6C Divide each side by 6
168/6=28=C ANSWER Christopher is 28 years old
K=2C=2(28)=56 ANSWER Kevin is 56 years old
CHECK
K-24=8(C-24)
56-24=8(28-24)
32=8(4)
32=32
