3I(99 + -90I + (-11 * -7i + 10I * -7i)) = 0
3I(99 + -90I + (77i + -70iI)) = 0
3I(99 + -90I + 77i + -70iI) = 0
(99 * 3I + -90I * 3I + 77i * 3I + -70iI * 3I) = 0
(297I + -270I2 + 231iI + -210iI2) = 0

Solving
297I + -270I2 + 231iI + -210iI2 = 0

Solving for variable 'I'.

Factor out the Greatest Common Factor (GCF), '3I'.
3I(99 + -90I + 77i + -70iI) = 0
