Solution for =a(x+y) equation:


Simplifying
0 = a(x + y)
0 = (x * a + y * a)
0 = (ax + ay)

Solving
0 = ax + ay

Solving for variable 'a'.

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

Add '-1ax' to each side of the equation.
0 + -1ax = ax + -1ax + ay
Remove the zero:
-1ax = ax + -1ax + ay

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

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

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

Factor out the Greatest Common Factor (GCF), '-1a'.
-1a(x + y) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0

Subproblem 2

Set the factor '(x + y)' equal to zero and attempt to solve: Simplifying x + y = 0 Solving x + y = 0 Move all terms containing a to the left, all other terms to the right. Add '-1x' to each side of the equation. x + -1x + y = 0 + -1x Combine like terms: x + -1x = 0 0 + y = 0 + -1x y = 0 + -1x Remove the zero: y = -1x Add '-1y' to each side of the equation. y + -1y = -1x + -1y Combine like terms: y + -1y = 0 0 = -1x + -1y Simplifying 0 = -1x + -1y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Solution

a = {0}
