Rewrite 3x+4y=15+6 so y is a function of x

3x+4y=15+6

Y=6 x=-1

3(-1)+4(6)=21

-3+24=21

Step-by-step explanation:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
