What is the value of y in the equation 6 + y = −3? a.−9 b.−3 c.3 d.9

Subtract 6 from both sides of the equation to get y by itself. This gives you y=-3-6 which becomes y=-9.

y=-9. your answer is -9.

Hope I helped.

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.
