Which equation is equivalent to 6x-2y= -10 a. 3x-y= -5 b. 12x - 4y=20 c. 2x-6y= -10 d. -3x+y= -10 e. 3x-2y= -5

Ihonestly don’t understand this at all

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

Solve x+3y=6 and 4x-6y=6 by elimination . show work !
