To solve this proportion, we need to cross multiply and solve for the variable:

Y + 2/7 = 1/3

Cross multiply to get:

3(Y + 2) = 7

3Y + 6 = 7

3Y = 1

Y = 1/3

Now, we can substitute Y = 1/3 into the other proportions:

Y = 1/3

1/3 = 1:6

3(1/3) = 1*6

1 = 6

This is not a valid proportion, so there is no solution for x in this case.

Please clarify or correct the proportions so we can further help.
