Question

Systems of equations I need help and show your work to

Answer 1

I started by using elimination to solve for x

3x + 9 = -3y became -2x - 2 = 0
-5x - 11 = 3y

then i soved for x

-2x = 2 x = 2/-2 x = -1

then i plug that back in for x and sove for y in one of the original equations

first equation
3(-1) + 9 = -3y 6 = -3y 6/-3 = y y = -2

second equation
3y = -5(-1) - 11 3y = -6 y = -6/3 y = -2

therefore your answers are x = -1 and y = -2
