Answer:
x > - 11
Explanation:
Isolate the variable, x. Note the <, treat it like a equal sign, what you do to one side, you do to the other.
First, subtract 14x and add 18 to both sides:
12x (-14x) - 18 (+18) < 14x (-14x) + 4 (+18)
12x - 14x < 4 + 18
-2x < 22
Next, isolate the variable, x. Divide -2 from both sides. Note that when you divide by a negative number, you must flip the sign:
(-2x)/-2 < (22)/-2
x < (22/-2)
x > -11
x > - 11 is your answer.
