For this equation first you should add +11 on both sides and the add -4/7w so you will have:
3/7w- 4/7w = 11 ⇒ -1/7w = 11 ⇒ w = 11* -7 = -77 so the answer is:
w = -77 :)))

Answer:
x = 4
Step-by-step explanation:
DE / XY = EF / YZ
5 / 10 = 2x-1 / 14
cross-multiply:
10(2x-1) = 14(5)
20x - 10 = 70
20x = 80
x = 4
