Answer:
and 
are like terms.
Step-by-step explanation:
Recall what "like terms" means in an algebraic expression: Those terms that have the same variables at exactly the same exponents.
so in the expression: 
the second term and the fourth one are like terms. Notice that both terms have the variables: 
with the variable "x" to the power 2, and with the variable y to the first power.
and are like terms.
Therefore, those are the only terms you can combine to reduce the expression.
Move the numbers with variables attached to one side, and the numbers to the other
x (-x) + 113 (-27) = 2x (-x) + 27 (-27)
2x - x = x
x = 113 (-27)
x = 86
