Answer:
x = -7
Step-by-step explanation:
-2x + 4 = 18
-2 is (obviously) a negative number so you'd need to make it positive, so that makes x a negative number as well. and -2x means x and -2 are being multiplied by each other.
18 - 4 = 14 so we should divide 14 by 2 to see what x equals.
14 divided by 2 = 7.
x = -7
