What is x in the equation 4x+0.4=4.4?

First step is to isolate the term that contains the unknown x to the left side. For this reason, we'll subtract 0.4 both sides:
4x = 4.4 - 0.4
4x = 4
Now, we'll divide both sides by 4:
x = 1.
Another way to solve this problem is to divide both sides by 4:
x + 0.4/4 = 4.4/4
x + 0.1 = 1.1
Now, we'll subtract 0.1 both sides:
x = 1.1 - 0.1
x = 1
The required solution of the given equation is x = 1.
