One million dollars on the 30th day, it amounts to more than the collective of pennys would.
X=10
12x-1=12+10x+7
2x=20
X=10
X= 10
This is because 180-95= 85 which would make 8x+5= 85
Subtract 5 from both sides and get 8x=80
Then, divide 8 from both sides and get x=10
I don't know if i'm right or what because I haven't learned binomial in like almost 4 years. (3x+y)?
