Hi there!
Let's solve this equation step by step!
[tex] - 4a + 4a + 3 = 8[/tex]
First we collect the terms (the variables 'a', which add up to 0).
[tex]3 = 8[/tex]
Obviously, this expression is FALSE, since 3 doesn't equal 8. Therefore the equation does not have any solutions. Whatever value of 'a' you plug into the equation, the right side of the equation will always be 5 bigger. Hence, the answer is zero.
