Answer:
1.) x = -3 2.) x = 4/3 3.) x = 698/77 or 9.1
Step-by-step explanation:
1.) 4 + 2x = -2
2x = -2 - 4
2x = -6
x = -3
2.) -1 (3x - 12) = 9x - 4
-(3x - 12) = 9x - 4
-3x + 12 = 9x - 4
-3x - 9x = -4 - 12
-12x = -16
x = 4/3
3.) x - 4 = 13 (6x - 54)
x - 4 = 78x - 702
x - 78x = -702 + 4
-77x = -698
x = 698/77 or 9.1
1. x = -3
2. x = 4/3
3. x = 698/77
4+2x=-2
-4 -4
2x= -6
/2 /2
x=-3
You have to get x alone on one side. Search up on yt "How to solve for x on two sides."
p - 2
Because the collar weighs two pounds, to find how much the dog would weigh without the collar, you simply have to subtract two pounds from the final count, represented by p.
