2(x + 4) = 4x + 3 - 2x + 5

Step-by-step explanation:

2x + 8 = 4x + 3 - 2x + 5

2x - 4x + 2x = 3 +5 -8

0 = 0

x = 0

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

answer is
