To evaluate the expression, we'll follow the order of operations (PEMDAS/BODMAS).

First, let's simplify what's inside the parentheses:

3.15 - (21/20) = 3.15 - 1.05 = 2.1

Now, let's continue evaluating the expression:

-5(2.1) + 7

Next, perform the multiplication:

-5 * 2.1 = -10.5

Finally, complete the addition:

-10.5 + 7 = -3.5

Therefore, the value of the given expression is -3.5.
