Answer:

[tex]\frac{3}{5}[/tex]

Step-by-step explanation:

In order to solve for this equation, we need to convert the 1 to a fraction so it becomes easier to work with. So here is your new equation:

[tex]\frac{2}{5} +x = \frac{5}{5}[/tex]

The 1 is converted to the fraction [tex]\frac{5}{5}[/tex] as the ratio of 5:5 = 1

With that said, we are going to subtract the [tex]\frac{2}{5}[/tex] form both sides of the equation to isolate the variable x from its coefficients.

[tex]\frac{2}{5} +x = \frac{5}{5} \\-\frac{2}{5}\\x = \frac{3}{5}[/tex]
