A: x = 2
B: x < 5
Step-by-step explanation:
Part A:
Substitute the given value and solve for x.
f(x) = 3(x +6)
24 = 3(x +6)
8 = x +6 . . . . . . divide by 3
2 = x . . . . . . . . . subtract 6
__
Part B:
Eliminate parentheses, solve the 3-step inequality.
2(x -4) > 4x -18
2x -8 > 4x -18
-8 > 2x -18 . . . . . . . subtract 2x
10 > 2x . . . . . . . . . . add 18
5 > x . . . . . . . . . . . divide by 2
The solutions for x include any value less than 5.
