Evaluate the expression by substituting the givin values for each variable

b
- for A = -2 and b = 8
a

So is it like this

b
- = -2 divided by -8
a

the way you put it, i think it should be...

b/a = 8/-2 = -4

Thanks manny.

no problem!

4x + 10 = 22

To evaluate the expression by substituting the given values, you can substitute the value of A with -2 and the value of b with 8 in the expression:

b
-

So, it becomes:

8
-

Now, if you substitute the values,

8
-

It means that you divide 8 by -2:

8 / -2

This gives the result:

-4

Therefore, the value of the expression with the given values substituted is -4.
