6ya-6xb=3xya+6xy\left(-\frac{1}{3}\right)-a\times 6xy
Multiply both sides of the equation by 6xy, the least common multiple of x,y,2,3.
6ya-6xb=3xya-2xy-a\times 6xy
Multiply 6 and -\frac{1}{3} to get -2.
6ya-6xb=3xya-2xy-6axy
Multiply -1 and 6 to get -6.
6ya-6xb=-3xya-2xy
Combine 3xya and -6axy to get -3xya.
6ya-6xb+3xya=-2xy
Add 3xya to both sides.
6ya+3xya=-2xy+6xb
Add 6xb to both sides.
\left(6y+3xy\right)a=-2xy+6xb

6ya-6xb=3xya-2xy-a\times 6xy
Multiply 6 and -\frac{1}{3} to get -2.
6ya-6xb=3xya-2xy-6axy
Multiply -1 and 6 to get -6.
6ya-6xb=-3xya-2xy
Combine 3xya and -6axy to get -3xya.
-6xb=-3xya-2xy-6ya
Subtract 6ya from both sides.
\left(-6x\right)b=-3axy-2xy-6ay
The equation is in standard form.
\frac{\left(-6x\right)b}{-6x}=-\frac{y\left(3ax+2x+6a\right)}{-6x}
