2) 7(x+y)+3(x-y) if x=6;y=10
3) -8(a+b)+4a-7b if a=7;b=6
4) 2x+y;if x=2;y=4
5) 9(2p-4q)if p=1/2;q=1/4 Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Evaluate the the following expression
1) 6c-7d+8 if c=5;d=2
---
Sub 5 for c and 2 for d
--> 6*5 - 7*2 + 8
= 30 - 14 + 8
= 38 - 14
= 24
============================
Do the others the same way.
