Here, given the values of x and y, we are told to evaluate the given expression
What we need to do here is to simply substitute the values of x and y into the given expression
Thus;
we have -x + 5y + 2x
By substitution, this becomes;
-(-4) + 5(8) + 2(-4)
= 4 + 40 -8
= 44 - 8
= 36
Given x = -4 and y = 8 , the expression -X +5y + 2x = 36
