Use elimination to solve the system:

\[
6x - 4y = 6
\]

\[
-6x + 3y = 0
\]

Answer (3)

6x and -6x cancel each other out. You are left with -1y=6 Therefore, y=-6
6x-4(-6)=6 6x+24=6 Subtract 24 from both sides.
6x=-18 Divide both sides by 6 X=-3
Final answers: x=-3 y=-6

6x+4y=6 -6x+3y=0
7y=6 y=6/7
use one of the equations above i picked the first one 6x+4y=6 6x+4(6/7)=6 6x+24/7=42/7 6x=18/7 x=3/7

To solve the system using elimination, we add the two equations to eliminate x , resulting in y = − 6 . We then substitute y back into the first equation to find x = − 3 . The solution is ( x , y ) = ( − 3 , − 6 ) .
