Answer: 
Step-by-step explanation:
The answer is 1/4 because when you add all the numbers up it equals 12 and B or C gives us 3 which simplifies to 1/4
Answer: b. Consolidate all credit cards onto a single card with a single interest rate.
Step-by-step explanation: Steps a, c and d are in correct order. First, we have to arrange our debts in order of paying them off. Second, we need to determine how much extra money we have each month that can be contributed to debt payment. And finally, we need to track our progress of paying debt. So, option b is not included in the steps.
Thus, the correct option is b. Consolidate all credit cards onto a single card with a single interest rate.
If you equate both, the y is eliminated:
-6x-3 = -x+2
Simplify this to find x:
-5x = 5
x = -1
Fill in x=-1 in either equation:
y = --1 + 2 = 3
So (-1,3) is the solution, it is where the lines intercept.
