Question

Evaluate the expression below for x = -4 and y = 8 -X +5y + 2x

Answer 1

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
