Answer:

Step-by-step explanation:

Goal 1:  Solve for x:  Subtract 6y from both sides.  This yields -4x = -6y - 30.

Change all the signs to +.  We get 4x = 6y + 30.  Dividing all terms by 4 yields x = (3/2)y + 15/2.

Goal 2:  Solve for y.  Add 4x to both sides.  Then 6y = 4x - 30, or y = (2/3)x - 5
