Y= -3 - 2x because all you have to do is move the 2x over to have an x and a y on different sides, and in order to do that you do the opposite so since it is a positive 2, you subtract it and make it negative
30 is greater than 3. So 30 > 3
There are 4 meatloafs and each loafs are cut into fourths or 4 pieces.
4 groups of 4
Or
4 * 2
Or
4 + 4 + 4 + 4
= 16
Expression: 3(x - 5) = 21
= 3x - 15 = 21
= 3x = 21 + 15
= 3x = 36
= x = 36/3
= x = 12
In short, Your Answer would be: 12
Hope this helps!
