Answer :
Since y does not contain the variable to solve for, move it to the right side of the equation, by subtracting y from both sides.
x = -y +3
Move all terms that don't contain y to the right side and solve.
y = x/2 - 1/2
x = -y +3
Move all terms that don't contain y to the right side and solve.
y = x/2 - 1/2
