Step-by-step explanation:
An equivalent expression is an expression which is equal to −(4 + 3i) + (2 + 2i). You can expand or simplify an expression to make an equivalent expression. Combine like terms - constants with constants and imaginary with imaginary - to simplify.
−(4 + 3i) + (2 + 2i) = -4 + 2 -3i + 2i = -2 - i
