Simplify the expression. (3-i)-(2+6i)?

Invisible numbers. I know the answer is 1-7i but I get lost in the process?

lol its not invisible numbers: imaginary numbers; i is the same thing as sqrt(-1) which obviously is not a real number; thats why its imaginary. Sometimes, its easiest just to think of the i as an x. like you do with normal algebraic equations, combine like terms (3-2) and (i-6i) which gives 1 – 7i. hope that helped!... Show More
