Answer:
(2,6)
Step-by-step explanation:
x-y=-4 -----> Get the one of the variables by themselves
x=-4+y -----> All i did was adding the y to the the other side to get x by itself
Now all you do is to substitute the in the equation into the other equation
x=-4+y --------------> 6(-4+y)-4y=-12
Then solve
Now since you have your y now all you need to do is to do the same thing
Substitute the y in for the other equation
Then there you go

Answer:
Cost of each eagle stamp = $0.25
Cost of each racoon stamp = $0.4
Step-by-step explanation:
Given:
Cost of 8 eagle stamp and 2 racoon stamp = $2.80
Cost of 3 eagle stamp and 4 racoon stamp = $2.35
Find:
Cost of each stamp
Computation:
Assume;
Cost of each eagle stamp = e
Cost of each racoon stamp = r
So,
8e + 2r = 2.80........... Eq 1
3e + 4r = 2.35 ........... Eq 2
Eq 1 x 2
16e + 4r = 5.6 .........Eq3
Eq 3 - Eq 2
13e = 3.25
e = 0.25
Cost of each eagle stamp = $0.25
8e + 2r = 2.80
8(0.25) + 2r = 2.80
2 + 2r = 2.80
r = 0.4
Cost of each racoon stamp = $0.4
