Good morning Sonny
y-4x=7
2y+4x=2
We need to solve -4x+y=7 for y
Now let's start by adding 4x to both sides
-4x+y+4x=7+4x
y=4x+7
Now substitute 4x+7 for y in 4x+2y=2 so we can find the value for x
4x+2y=2
4x+2(4x+7)=2
12x+14=2
Add -14 to both sides
12x=14-14=2-14
12x=-12
Now divide 12 to both sides so we can find x
12x/12=-12/12
x=-1
Now we need to find the value for y by substitute -1 for x in y=4x+7
y=4x+7
y=(4)(-1)+7
y=3
Work done ;)
Answer : x=-1 and y=3
(-1,3)

I hope that's help :0
The way you would find how much one pound costs is divide .98 by 3 1/2. 3 1/2 in decimal form is 3.5 so .98 ÷ 3.5 = .28
So one pound of bananas would cost $0.28
Hope that helped!
