Answer:
She will get 12 books from the store
Step-by-step explanation:
We can use ratio's to solve
2 books out x books out
------------------- =-----------------------------
3 books in 18 books in from Val
Using cross products
2 * 18 = 3 *x
Divide each side by 3
2*18 /3 = 3x/3
2*6 = x
12 =x
She will get 12 books from the store
x-3y=7 2x-6y=12
You can multiply -2 in the first equation like this.
x+6y=7
2x-6y=12
Now you can eliminate 6y and -6y so cross them out and do x-2 which is -1 and 7-12 which is -5 -1/-5 would be .2
