Answer:
y = - 3
Step-by-step explanation:
Given
=
( cross- multiply )
9(y + 2) = 3y ← distribute left side
9y + 18 = 3y ( subtract 3y from both sides )
6y + 18 = 0 ( subtract 18 from both sides )
6y = - 18 ( divide both sides by 6 )
y = - 3
Multiply numerator and denominator by the conjugate of the denominator
Denominator: -10 + 8i
Conjugate of the denominator: -10 - 8i
Operation:
[9 +7i] / [-10 + 8i] * [-10 -8i] / [-10 - 8i] = [-90 - 72i - 70i +56] / [100 + 64] =
[-34 -142i] / 164 = [-17 -71i] / 82
