125/42
2.976
You would just do 4 x 7, which means there are 28 combinations.
Answer:
x = 4 and y = 1
Step-by-step explanation:
3x+2y=14
2x-4y=4
We can solve them by canceling out one variable so we only have one variable left. Let's cancel out y by doubling the first equation. We get:
6x + 4y = 28
add that on to the second one and we get:
8x = 32
x = 4
We plug in x and get that:
y = 1
So in the end we get
x = 4 and y = 1
