Answer: y=-3x/4-1
Step-by-step explanation:
I belive the answer is 4 or maybe 6 I think 6 is correct
The solution is (-3,5)
The solution to a system of linear equations is just the intersection point
For this case what you should do is solve the problem using for example a rule of three
60% ---> 36
100% ---> x
Clearing x we have:
x = (100/60) * (36) = $ 60
Checking the result:
40% of 60 is
(0.40) * (60) = 24
60-24 = 36 $
