For number 38 the column would be 25ft high since 175ft of it is below sea level. Anything that's "below sea level" is a negative number. Anything that's "above sea level" is a positive number. So you're basically just doing 200 minus 175 to get your answer.
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.
