Question

Help me with the geometry work

Answer 1

Explanation:

The thing you have to realize is that the diagonals of a parallelogram bisect each other. So DF = BF. With that fact, you get

4y + 19 = 10y - 11 Add 11 to both sides

4y+19+11 = 10y-11+11 Combine

4y + 30 = 10y Subtract 4y

4y-4y +30 = 10y - 4y Combine

30 = 6y Divide by 6

y = 30/6

y = 5
