Set up the system of equations:


We'll use elimination to solve this system of equations.
Take the coefficients for y in both problems. Multiply one of them by -1:

Since this coefficient is taken from the first problem, we'll multiply the entire second problem by this negative coefficient:

Take the coefficient for y in the second problem and multiply the entire first problem by that coefficient:

Your system should now look like this:


Combine these two equations to cancel out y:

Divide both sides by 5 to get x by itself:
A fairy soda costs $1.50.Because we know the value of one of the variables, we can plug it into one of the equations:


Subtract 12 from both sides:

Divide both sides by 5 to get y by itself:
A fairy hotdog costs $3.75.

Use the rule of 3 simple
1680 beats ------- 60 min.
x beats -------------- 1 min.
----------------------------------
x = (1680*1)/60 = 1680/60 = 168/6 = 28 beats per minute
hope helped
