Answer:
infinitely many solutions
Step-by-step explanation:
I assume that you meant
3x = -12y + 15 and x + 4y =5 (you accidentally omitted the 'y')
Multiplying the second equation by 3 yields
3x + 12y = 15
... which is identical to the first equation. Thus, the two lines coincide, and we conclude that there are infinitely many solutions.
Answer:
k = 24
y = 24x
Step-by-step explanation:
72/3 = 24
y = 24x
72 = 24(3)
72 = 72
Hope this helps!
