    Since you have a denominator of 3, first multiply both sides by 3. Then add or subtract the terms on the right side to move them to the left side.

    y = 2/3 x - 7 Multiply both sides by 3: (3)y = (3)(2/3 x - 7) What do you get? Remember to distribute the 3 on the right side.

    so 3y = 2x -21

    Now since you want everything on the left side, subtract 2x from both sides, and add 21 to both sides.

    3y = 2x - 21 -2x + 21 -2x + 21 -------------------------- -2x + 3y + 21 = 0 If you don't like to have a negative sign at the beginning (with the x term), you can multiply both sides by -1 and get 2x - 3y - 21 = 0
