Question

Lawson planted a tree when it was 14 inches tall and it will grow 3 inches per year. Ezra planted a tree when it was 8 inches tall and it will grow 5 inches per year. Determine how many years it will take for the trees to be the same height. Thanks

Answer 1

Answer: 3 years.
Explanation:
y = number of years
3y+14 = 5y+8
Subtract 3y from both sides.
14 = 2y+8
Subtract 8 from both sides.
6 = 2y
Divide by 2 on both sides to solve for y.
y = 3
