SHOW ALL STEPS AND WORK.
a. 3x  8 = 55
b. 7 + 2x = 4x  11
c.  2(x + 3) = x
d. 3(4  2x) = 24
e. 4x + 3 = 31
f.  5  y = 16
g. 4  2x = 16
h. 3x  7 = 5x + 7
i. 4(3  x) =  6x 7) A teacher performs a magic trick with his
class. He tells his class to pick a number (any
number). Subtract 5 from the number.
Multiply your result by 10. Add 16 to that
product. Divide this by 2. And finally add 17.
USING ONLY ALGEBRAIC NOTATION
(pick x as your original number) walk your
way through this trick and then describe how
the final answer relates to the original number
chosen by the student.
