Answer:
2 or 4
Step-by-step explanation:
Since I do not quite understand what you mean by X X, I could think of two answers. If you are doing 5 times X=20, then X = 4, but if you are trying to do 5 times x times x, then x=2.

Okay, so let's break it down step-by-step:
1) distribute the 2 inside the parenthesis (2*x and 2*5) it gives you 2x-10
2)So now you're equation is Y-3=2x-10. You want Y by itself if you want it in Y-intercept form. So add three on each side. 3 cancels out on the right.
Y-3=2x-10
+3 +3
-----------------
Y= 2x+13
3) And there you go, Y=2x+3 is the answer
It's b. Group all the pounds together and all the volumes together. Small packages weigh 30 lbs (30x), lg pkgs weight 65 lbs (65y) and together they weigh at most 3800 lbs. So 30x + 65y <= 3800 (they divided each of those terms by 5 to get 6x + 13y <= 760). Next take the volumes: small pkgs have a volume of 4 ft^3 (4x) and lg pkgs have a volume of 9 ft^3 (9y) and together they are no more than 400 ft^3. So 4x + 9y <= 400. It's b.
