Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-1x' to each side of the equation.
ax + ay + x + -1x + y = 0 + -1x

Combine like terms: x + -1x = 0
ax + ay + 0 + y = 0 + -1x
ax + ay + y = 0 + -1x
Remove the zero:
ax + ay + y = -1x

Add '-1y' to each side of the equation.
ax + ay + y + -1y = -1x + -1y

Combine like terms: y + -1y = 0
ax + ay + 0 = -1x + -1y
ax + ay = -1x + -1y

Reorder the terms:
ax + ay + x + y = -1x + x + -1y + y

Combine like terms: -1x + x = 0
ax + ay + x + y = 0 + -1y + y
ax + ay + x + y = -1y + y
