Use substitution to combine equations. rewrite so that one side is equal to 0.

Using substitution, I merged the two equations setting them equal to each other:

Then, in order to make one side zero, all you have to do is subtract 3 from each side.

Your answer would be:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
