First, let's substitute the values of r and s into the expression:
3r/s - 2
= 3(-3)/5 - 2
= -9/5 - 2
To combine these fractions, we need a common denominator (5 in this case).
= (-9 - 10)/5
= -19/5
Therefore, the value of the expression when r = -3 and s = 5 is -19/5.
Evaluate the expression for r = -3 and s= 5.
3r over s -2
