The first equation, 27 - 9x = - 7y, is equivalent to => 27 + 7y = 9x
The second equation is 45 +7y = 9x
You can see that thas system has not solution.
Those expressions represent parallel lines, so they never intercept each other, which means there is not solution.
Also you can subtract the two equations and get::
27 + 7y - 45 - 7y = 9x - 9x
=> 27 - 45 = 0
=> 27 = 45 which means the system has no solutions.
Answer: the system does not have any solution.

Answer: 4/9
Step-by-step explanation: we are going to multiply side to bottom so that would be 2/3x3 which equals 6/9 then you multiply the multiplication ( 6/9) by the 2/3 which equals 12/27. the GCF of 12 and 27 is 3. so when you simplify you get 4/9. mark me brainiliest pls
