The Charles current age is 10 years old, if in 20 years Charles will be three times as old as he is now.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
In 20 years, Charles will be three times as old as he is now.
Let's suppose the current age of Charles is x years
Then, according to the problem, we can frame a linear equation in one variable:
x + 20 = 3x
2x = 20
x = 10 years
Thus, the Charles current age is 10 years old if in 20 years Charles will be three times as old as he is now.
