Question

Sendo Z1 = 3x + 8i e Z2 = -6 + 8i, determine o valor de x, sabendo que Z1 = Z2. a)6 b) -2 c) -3 d) 8

Answer 1

$\mathsf{Z_1=Z_2\implies~3x+8i=-6+8i}\\\mathsf{3x=-6}\\\mathsf{x=-\dfrac{6}{3}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{x=-2}}}}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{\maltese~~alternativa~~b}}}}}$
