Answer:
Explanation:
Omar bought 15 pizzas in May.
In May, he bought 3 more than twice the number that he bought in April.
Since we don't know how many he bought in April, let X = the number of April pizzas.
Then, 15 = 2X + 3
Now you can subtract 3 from both sides, then divide both sides by 2 to leave X by itself and discover what it equals.
