Chase was trying to solve for x and y. he knows that the value of x is 3 times the value of y and that half of x plus twice y is equivalent to –14.
which system of equations could he use to solve for x and y?
a. 3 y = x
12 x + 2 y = –14
b. 3 x = y
12 y + 2 x = –14
c. 3 y + x = –14
12 x = 2 y
d. 3 x + y = –14
12 y = 2 x
