Question

3x=9 - 6y
3x+8y=9

Answer 1

Take \(-6y\) from the first equation to the other side. Your system of equations will then be:
\(3x+6y=9\) (1)
\(3x+8y=9\) (2) Subtract (2) from (1), you get:
\(-2y=0\implies y=0\). Now substitute \(y=0\) in either equation, you get \(3x=9 \implies x=3\).

Answer 2

ok, so move the -6y to the other side to get 3x+6y=9. For this specific problem, multiply the first equation by -1 to get -3x-6y=-9. Add the two equations up to get 2y=0. y=0.
Substitute 0 into the second or first equation. I will do the first equation. 3x=9-6(0). 3x=9. so x=3.

Answer 3

so whats the answer??? im confused

Answer 4

\(x=3\) and \(y=0\) is your answer.

Answer 5

omGGGGGGGGGGGGGG THANKSSS SO FREAKING MUCH!

Answer 6

:))))))))))))))) delighted to help.

Answer 7

anwarA can you help me again?

Answer 8

If you give me a medal :D

Answer 10

so desperate.

Answer 11

lol

Answer 12

you both got medals!!! from me

Answer 13

and u just bumped me up a lvl! yay!

Answer 14

-10x - 6y=0
-4x - 6y=54

Answer 15

Congrats some1!!

Answer 16

Subtract (2) from (1), you should get \(-6x=-54 \implies x=9\). Plug this in either equation, you find \(-90-6y=0 \implies y=15\).

Answer 17

thanks but whats x?

Answer 18

x=9

Answer 19

Wait!

Answer 20

ugh!! to late i already got it wrong flutterkkkk! =((((((((((
