Answer:
Jack is incorrect. The correct answer is 2
Step-by-step explanation:
The question is given as:
4x-24 / (y+w) where x=5, y=3 and w= -5
Substitute values of x, y and w in the equation as;
4*5 - 24 / (3+-5)
20 - 24 / (-2)
-4 / -2 = 2
Jack's answer is 7 which is wrong. The correct answer is 2
2 is correct because you have substituted the real values of x,y and w in the expression and performed the operation right.
