Multiply the first equation by 3 and the second equation by 2:
Subtract the two equation to get rid of the x variable:
Use the value of y to determine the value of x: for example, using the first equation we have
Bill's statement does not make sense because it is incorrect:
7/12 customers bought pretzels
3/10 OF those customers bought low salt pretzels (x)
3/10 of 7/12 = x
(the word "OF" normally refers to multiplication and he variable x represents low salt pretzels)
3/10 times 7/12 = x
21/120 = x
Simplify: 7/40
To be correct, Bill would have to say that 7/40 of the customers bought low salt pretzels, but instead he had said 7/30.
P=2L+2W
P-2W=2L
P/2-W=L
L=P/2-W
