ANSWER:
35
STEP-BY-STEP EXPLANATION:
We have the follwing function:
[tex]x-y=10[/tex]Now, if the value of x is less than 50, so that the difference is equal to 10, then:
[tex]\begin{gathered} 49-y=10 \\ y=49-10=39 \end{gathered}[/tex]Therefore, the value of y must be less than 39, the only option that is satisfied with this is 35
