First, I'd like to state there are many possibilties to for this solution.
Okay, 9/3 + 3 = -1b
Lets check.
PEMDAS!
9/3 is = 3
So:
3 + 3 = -1b
Then combine like terms:
6 = -1b
Following PEMDAS, divide -1 on both sides so..
-6 = b or b = -6
So, 9/3 + 3 = -1b works!!!
Answer:
x = 11, y=-½
Step-by-step explanation:
Simultaneous equations - subtract the first equation from the second.
x + 4y = 9
-(x - 2y = 12)
6y = -3
y = -½
Substitute y
x + 4(-½) = 9
x + -2 = 9
x = 11
2 1/4 + 1 1/2
2 + 1 = 3
1/4 + 1/2 = 1/4 + 2/4 = 3/4
so ur answer is 3 3/4 lbs of cheese in total
