x-2/5=7 \\

x=7+2/5\Longrightarrow x=\dfrac{35+2}{5}=\boxed{\dfrac{37}{5}}

[/tex]

Hope this helps.

Answer:

[tex]x = \frac{37}{5}[/tex]

Step-by-step explanation:

First, let's change that 7 on the right side into a friendly denominator. We'll do that by converting it into fifths! Since 7 * 1 = 7, we can multiply 7 by [tex]\frac{5}{5}[/tex] to get [tex]\frac{35}{5}[/tex]. We now have [tex]x-\frac{2}{5} = \frac{35}{5}[/tex]. From here, we just combine like terms!

[tex]x -\frac{2}{5} + \frac{2}{5} = \frac{35}{5} +\frac{2}{5}[/tex]

[tex]x = \frac{37}{5}[/tex]
