1). 3y=11-2x

2). 3x=y-11

Using equation 1: y = (11-2x)/3

Substituting into equation 2

3x = (11-2x)/3 - 11

x = (11 -2x)/9 - 11/3

x + 2x/9 = 11/9 - 11/3

11x/9 = 11/9 - 11/3

solve for x

Then plug x into either equation 1 or 2, and solve for y

2) Use a similar procedure, as shown in problem 1
