(a+6)+3bi=6-7i Find real numbers a and b such that the equation is true.

hartnn (hartnn):

just compare real and imaginary parts: so a+6=6 a=? 3b=-7 b=?

OpenStudy (anonymous):

No helping me yet, I am really lost on this problem. Each one builds on the last so I am not seeing the results

hartnn (hartnn):

which part did u not understand ?

OpenStudy (anonymous):

Im supposed to solve for a and for b, but I struggle with imaginary parts and seeing the big picture.

hartnn (hartnn):

imaginary terms are the terms with i so here we had 3bi=-7i --> 3b=-7 can u find b now ?

OpenStudy (anonymous):

a=0 and b=-2.33?

hartnn (hartnn):

yup, u are correct :)
