4(3s) + 2(-t)

if s = 1/2 and t = -3, what would the answer be?

The expression would be = to 0.

Step-by-step explanation:

Starting with -4(3s) + 2(-t), substitute (1/2) for s and (-3) for t:

                    -4(3/2) + 2(+3)

This gives us:

                       -12/2 + 6 = 0              

17.08
