Solve independent system equations for: 5x-9y=-6510x-3y=20x=?y=?

1 answer:

3 0

5x-9y=-65
10x-3y=20

Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x

21y=-150
Divide the -150 by 21
Y=-7.14

Plug the y into the original equation. (Either one)

5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144

I hope this is right

otez555 [7]

The statement is totally false.

$\neg P\lor\neg Q \equiv \neg(P \land Q) \not\equiv P\land Q$

because (P and ¬P) is a contradiction.

Brandon x-18

Michael 3x-18

9 (x-18)=3x-18

9x-9.18=3x-18

9x-3x=9.18-18

6x=8.18

x=8.3

x= 24
