1. Read the following word problem, then choose which linear equation models the problem.
The sum of the ages of an older sibling and a younger sibling is 16. Four years from now, the of the younger sibling will be the same as the age of the older sibling was two years ago. Find the present age of each sibling.
A. 4x = 14 - x + 16
B. x + 14 - x = 16 + 2
C. x - 4 = 14 + x
D. x + 4 = 14 - x
2. Read the following word problem, then choose which linear equation models the problem.

A. 2w = 338
B. 2w • w = 338
C. 2w + 2w = 338
D. 2(w + w) = 338
3. Read the following word problem, then choose which linear equation models the problem.
