Question

Mr. Boon went to the fair and bought 2 churros (x) and 3 sodas(y) for a total of $12.

The equation 2x + 3y = 12 demonstrates the situation.
If the sodas cost $2 each, how much do the churros cost? (Don't forget the units)

Answer 1

$3

Explanation:

Plug in 2 for y, so you get 2x + 3(2) = 12, and that simplified would be

2x + 6 = 12. Next, subtract 6 from both sides, so you get 2x = 6. Divide 2 by both sides to get 3!
