A solution set is the set of all variables that makes the equation true.
Given equation:
[tex]25x\text{ = 40}[/tex]Let us solve for x:
[tex]\begin{gathered} 25x\text{ = 40} \\ Divide\text{ both sides by 25} \\ \frac{25x}{25}\text{ = }\frac{40}{25} \\ x\text{ = }1.6\text{ }or\text{ }\frac{8}{5}\text{ or 1}\frac{3}{5} \end{gathered}[/tex]Answer: Option B
