You buy one shirt for $22 and two pairs of shorts. your total cost is $56. assuming both pairs of shorts cost the same amount, what is the price of one pair of shorts?
what is the correct equation and solution for this problem?
2x - $22 = $56; x = $34
2x + $22 = $56; x = $34
2x - $22 = $56; x = $17
2x + $22 = $56; x = $17

2x + 22 = 56
2x = 56 - 22
2x = 34
x = 34/2
x = 17

We know that the shirt and the two shorts both combine to yield a total cost of $56. This means that the first and third equations are not possible. From there we are left with two options. To show the correct answer, let's solve for x ourselves:

2x + 22 = 56
2x = 56 - 22
2x = 34
x = 34/2
x = 17

Therefore each of the shorts cost $17 making the last equation correct.

Hope this helps!
