What is the proper way to set up the equation to begin solving?
y = 6x − 11
−2x − 3y = −7
-2(-11) -3y= -7
-2(6x-11) -3y = -7
-2x -3(11) = -7
-2x - 3(6x-11)= -7

What is the proper set up to solve the equation?
-7x -2y= -13
x = 2y+11
-7(11) -2y = -13
-7(2y +11)-2y = -13
-7x -2(11) =-13
-7x - 2(2y+11)= -13
