SAT Question 1a621af4: Linear Inequalities answer and explanation with Desmos solution

It's given that a number $x$ is at most $2$ less than $3$ times the value of $y$. Therefore, $x$ is less than or equal to $2$ less than $3$ times the value of $y$. The expression $3y$ represents $3$ times the value of $y$. The expression $3y-2$ represents $2$ less than $3$ times the value of $y$. Therefore, $x$ is less than or equal to $3y-2$. This can be shown by the inequality $x\le 3y-2$. Substituting $-4$ for $y$ in this inequality yields $x\le 3\left(-4\right)-2$ or, $x\le -14$. Therefore, if the value of $y$ is $-4$, the greatest possible value of $x$ is $-14$.
