What are you solving for? Answer: y!
what is in the way if the y being "alone"? Answer: the factor 5 and the term 27!
what is the 27 doing to the y? Answer: adding!
what is the opposite of adding 27? Answer: subtracting 27!
what is the 5 doing to the y? Answer: multiplying!
what is the opposite of multiplying By 5? Answer: diving by 5!
therefore, subtract both sides by 27 and then divide both sides by 5.
Problem: you never wrote the other side of the equation so I cannot solve.
If you wanted the equation evaluated I will have to know the value of y.
