Question

(4 - 3x) is greater than or equal to -9

Answer 1

x ≤ 13/3

Explanation:

4 - 3x ≥ -9

Isolate the variable, x. Treat the ≥ sign as an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 4 from both side:

4 (-4) - 3x ≥ -9 (-4)

-3x ≥ - 9 - 4

-3x ≥ -13

Next, divide -3 from both sides. Note that when you divide by a negative sign, you must flip the sign:

(-3x)/-3 ≥ (-13)/-3

x ≤ (-13)/(-3)

x ≤ 13/3

x ≤ 13/3 is your answer.
