If a= -2, we plug -2 in replacement of a.
7(-2) + 3 = ?
Multiply before adding.
-14 + 3.
-11 is the answer for A.
If y= -8, we plug in -8 in replacement for y.
-3 x -8 (multiplying two negatives makes a positive).
-24 -(9) = ?
Subtracting a negative from a negative is basically adding to the negative.
-33 is the answer for Y.
I hope this helps!
