Classifying 8+3(a4)=08 + 3(a - 4) = 0

To accurately classify the linear equation 8+3(a4)=08+3(a-4)=0, first distribute the 33 to eliminate the parentheses, yielding 8+3a12=08+3a-12=0. Combining the constant terms simplifies this to 3a4=03a-4=0. Adding 44 to both sides of the equation produces 3a=43a=4. Finally, dividing by 33 isolates the variable to provide the single valid solution a=43a=\frac{4}{3}. Because this equation is satisfied by only this specific numerical value, it is classified as a conditional equation.
