Question

Solve the following inequality: -20 < 4 - 2x
A. 8 >x
B. 8 C. 12 > x
D. 12

Answer 1

-20 < 4 - 2x (subtract 4 from both sides)

-24 < -2x (divide each side by -2)

12> x (when you divide by a negative number, the inequality flips)

x< 12 ( I always put it so x is first)

so the answer is C
