Graphing and Magnitude of a Complex Number

A modulus of a number is the distance from the origin to the number's point on a graph. We use $|z|$ to denote the modulus of $z$. To figure out the modulus we use the equation $\sqrt{x^2+y^2}$. For example: $$|2+i|\\ =|2+1i|\\ =\sqrt{(2)^2+(1)^2}\\ =\sqrt{4+1}\\ =\sqrt{5}$$

Using this information, solve for $z:$ $$z-|3+4i|=0$$
