Find all integers x (if any) that make the statements in parts (a)–(k) true.
a. x2 = 9
b. x2 = –9
c. –x ÷ –x = 1
d. –x2 is negative.
e. –(1 –x) = x – 1
f. x – 3x = –2x
g. –3(x + 2) = –3x + 6
h. (2x – 1)2 = (1 – 2x)2
i. x3 = –29
j. –6x > –x + 20
k. –5(x – 3) > –5
l. If x > –2, find the values of 3 – 5x
m. If x < 0, find the values of 2 – 7x
