Answer: 20 months
Step-by-step explanation:
x months times y for views over 1 month = 9000000 views
3 x 150000(views per video) = 450000
9000000/450000= 20 months
The equation in standard form would be,

All you have to do is move -2/7x to the other side.

-x + 5y = 8
multiply this equation by 3
-3x + 15y = 24
now add it to the other equation ( elimination)
-3x + 15y = 24
3x + 7y = -2
-----------------------
0x + 22 y = 22
divide each side by 22
y =1
substitute into -x + 5y =8 to find x
-x + 5(1) = 8
-x + 5 = 8
-x =3
divide by -1
x =-3
Answer (-3,1)
