Question

solution
simplify the expression $(3j + 1) - (4 + 2j)$
your answer
$1j - 3$

Explanation:

Step1: Distribute the negative sign

We have the expression \((3j + 1)-(4 + 2j)\). Distribute the negative sign to the terms inside the second parentheses: \(3j + 1-4 - 2j\).

Step2: Combine like terms

Combine the \(j\)-terms and the constant terms separately. For the \(j\)-terms: \(3j-2j = j\) (or \(1j\)). For the constant terms: \(1 - 4=-3\).

Step3: Write the simplified expression

Putting the combined terms together, we get \(j-3\) (which is the same as \(1j - 3\)).

Answer:

\(j - 3\) (or \(1j - 3\))
