Solve for a over the real numbers:

abs(5 a - 4) = a

Split the equation into two possible cases:

5 a - 4 = a or 5 a - 4 = -a

Subtract a - 4 from both sides:

4 a = 4 or 5 a - 4 = -a

Divide both sides by 4:

a = 1 or 5 a - 4 = -a

Add a + 4 to both sides:

a = 1 or 6 a = 4

Divide both sides by 6:

**a = 1 or a = 2/3 Their product is simply: 1 x 2/3 =2/3**
