Let's substitute the values of x and y into the expression:
5(2)(3) + 4((-1/2) - (-1))
Simplify:
5(2)(3) + 4((-1/2) + 1)30 + 4(1/2)30 + 2= 32
Therefore, when x = -1/2 and y = -1, the expression 5x2y3 + 4(x-y) equals 32.
Let's substitute the values of x and y into the expression:

Simplify:
5(2)(3) + 4((-1/2) + 1)
30 + 4(1/2)
30 + 2
= 32
Therefore, when x = -1/2 and y = -1, the expression 5x2y3 + 4(x-y) equals 32.
