Carl present age is 10 years while Dennis present age is 19 years.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent Carl present age and y represent Dennis present age, hence:
x + y = 29 (1)
Also:
After 6 years:
x + 6 = y - 3 (2)
From both equations:
x = 10, y = 19
Carl present age is 10 years while Dennis present age is 19 years.
