Decide whether the given number is a solution to the equation.

$2x + 3x + 2= 10$; $x = \frac{8}{5}$

Is $x = \frac{8}{5}$ a solution?

Help, I don't understand the question and have no idea how to even check if the solution is true or false.

If $x=\dfrac85$ then $2x=\dfrac{16}5$ and $3x=\dfrac{24}5$,

so $2x+3x+2=\dfrac{16}5+\dfrac{24}5+2=\dfrac{16+24}5+2=8+2=10$,

so $x=\dfrac85$ is a solution.
