Answer:
b=2
Step-by-step explanation:
-12+3b-1=-5-b
Combine like terms
-13 +3b = -5-b
Add b to each side
-13+3b+b = -5-b+b
-13+4b = -5
Add 13 to each side
-13+13 +4b = -5+13
4b = 8
Divide by 4
4b/4 = 8/4
b = 2
Answer: 143 hamburgers and 429 cheese burgers
Explanation:
Call h and c the number of both items.
(h-hamburger and c-cheeseburger)
h + c = 572
c = 3h
Sub the second into the first
h + 3h = 572
4h = 572
Divide both sides by 4
h = 143 hamburgers
Use this back into the second equation
c = 3 • 143 = 429 cheeseburgers
The answer is 1,1500 because you ha e to subtract the lowest to highest number
