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.
Answer:
3(x-1)+7=11
3x-3-7=11
3x-10=11
3x=11+10
x=21/3
x=7
Step-by-step explanation:
To determine the factor pairs for the number 30, simply find out the smallest set of numbers that will multiply to give 30, you would need to break down composite numbers to do this.
30 = 6 • 5 = 2 • 3 • 5.
These all are prime numbers that when multiplied together equals 30.
