$8
Step-by-step explanation:
for a discount of 20% we require to calculate 20% of $40
20% =
= 0.2, hence
discount = 0.2 × $40 = $8
-2(x + 3) = 8
Multiply -2 with x and 3
-2x -6 = 8
Now add 6 to both sides
-2x -6 = 8
+6 +8
-2x = 16
Lastly divide -2 from both sides to find x
-2x = 16
—— —-
-2x -2x
X = -8
