Giving brainliest! solve for x: 2x + y = 1

2x + y = 1

subtract y from each side

2x+y -y = 1-y

2x = 1-y

divide by 2 on each side

x = (1-y)/2

step-by-step explanation:

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
