I'm stumped on this question.
"The expression 2x+9 is equal to 9 for some value of x. Without finding the value of x, determine the values for each of the following expression. Show how you arrived at each answer."
A) 4x+12 = [2(2x+9)]- 6 2*9-6 = 12
B) 2x+9 = 9
C) 2x+9 = 9
D) -6x-18 = -3(2x+9)+9 = -3(9)+9 = -18
E) 2x+1 = 2x+9-8 = 9-8 = 1
F) 10x+32 = 2(2x+9)+14 = 2*9+14 = 32
