7x + y = 7
b
5x + 2y = -14
7x - y = 7
с
5x - 2y = -14
7x + y = 7
d
5x - 2y = -14
7x - y = 7

x+14

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
