For a math game, Kyle has 5 cards that show the numbers 1 – 5. He will place 2 of these 5 cards on his paper to make a fraction. By using different cards, Kyle can make many different fractions. What four fractions can be made with the cards that have values less than 12?

Adding all of these should equal to 180 from the way the angle is set up.

So the equation should be:

(3x + 2) + (2x + 5) + (2x - 9) = 180

You can remove parentheses as it doesn’t affect the equation since it is all addition.

Let’s first add the common variables together.

3x + 2x + 2x = 7x
2 + 5 + (-9) = -2

So now we should have:

7x - 2 = 180

Now add 2 to both sides.

7x = 182

Divide both sides by 7 to isolate x.

x = 26

So x is 26.
