Kendrick is 1 year older than 3 times his daughter's age. In 4 years, he will be 7 years less than 3 times as old as his daughter will be. Find their ages.
Let Kendrick's age be x and his daughter's age be y. We can use the information in the problem to write a system of equations.
x = 3y + 1
x + 4 = 3(y + 4) - 7
x = 3y + 1
x = 3y + 1
This equation has infinite solutions, so any ordered pair (x, y) would solve this problem.
