I think its 2 because if you divide 20,000 over 1000 you get 2. If you do that for the other values, you would also get 2.
Okay
1 yes and yes

Answer:
the correct answer is3 1/2
Hi Mark
3x+y=4
2x+y=5
Solve 3x+y=4 for y
Add -3x to both sides
3x+y-3x=4-3x
y=-3x+4
Substitute -3x+4 for y in 2x+y=5
2x+y=5
2x-3x+4=5
Simplify both sides of the equation
-x+4=5
Add -4 to both sides
-x+4-4=5-4
-x=1
Divide both sides by -1
-x/-1= 1/-1
x=-1
Substitute -1 for x in y=-3x+4
y=-3x+4
y=(-3)(-1)+4
Simplify both sides of the equation
y=7
Answer: (-1,7)
I hope that's help ! Have a great weekend :)
