Question

please answer this quickly and solve it by using elimination or substitution!!! you will also need this equation to solve 6x-y=20. the whole problem will look like this. With the first equaton on top and the second on the bottom.

3x+2y=40

6x-y=20

Answer 1

x=0, y=20........

Answer 2

iam noy able to solve for x in an equation y= 7E-05x+0.0979 the equation was obtained in an excel sheet

Answer 3

3x+2y=40

2y=40-3x

y=20-(3/2)x

--------------------------------------

6x-(20-(3/2)x)=20

6x-20+(3/2)x=20

6x+(3/2)x=40

(15/2)x=40

x=16/3

--------------------------------------

6(16/3)-y=20

32-y=20

-y=-12

y=12

-------------------------------------

6(16/3)-(12)=20

Answer 4

You're an idiot for not getting this one.

Answer 5
