Final answer:
Without additional information about line q, such as its slope or an equivalent expression, we cannot determine the value of x that makes line p parallel to line q.
Step-by-step explanation:
To find the value of x that makes lines p parallel to line q, we need more information. Typically, parallel lines have the same slope if they are linear equations in the slope-intercept form y = mx + b, where m represents the slope and b represents the y-intercept. Since we are only given the expression p = 3x + 24 and not a corresponding expression or slope for line q, we cannot determine the value of x that would make p parallel to q with the current information provided.
