Question

Solve the system using elimination. Make sure to show/explain your work for credit.

2x + y = 4
2x + 3y = 0

Answer 1

y=4 and 3y=0

Answer 2

idk..

Answer 3

Subtract the bottom equation from the first equation so you have an equation in one variable. Solve for Y and substitute back into one of the original equations to get x.

Answer 4

it's basically like where you subtract the terms that share the same variable. for example, \(2y - 2y\). so you would need to do the same with \(y\) and \(3y\), including \(4\) and \(0\).

Answer 5

2x + Y = 4
-2x -3Y = 0

-2Y = 4 Solve for Y. Then substitute into 2x + Y = 4 to get x.

Answer 6

\(2y - 2y = ?\)
\(y - 3y = ?\)
\(4 - 0 = ?\)

Answer 7

Are you good?
