Mrs. galindo found a first edition copy of the book 1984 on sale. she paid $75, which was $7 more than 1/3 of the original price. what was the original price? let p represent the original price of the book. which equation best represents the situation given?

(a 7 + 1/3p = 75 )

(b 7 - 1/3p = 75 )

(c (1/3)(75) = 7x)

(d 75x + 1/3 = 7)

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
