To solve the equation \(-8j = -5j - 3j\), we can first simplify the right side.
Combine the terms on the right side:
\[ -5j - 3j = -8j \]
Now the equation becomes:
\[ -8j = -8j \]
This statement is always true, meaning that every value of \(j\) satisfies the equation. Therefore, there are infinitely many solutions to the equation.
