>can you help me brah?

yes

>>

>>7788878

will you please?

>>

>>7788862

divide both sides by 1-4i and take the imaginary part

>>

>>7788881

No.

>>

>>7788888

Holy shit check those bodacious quints

>>

>>7788881

Just divide both sides by (1-4i)

>>

>>7788862

divide both sides by (1-4i)

multiply by the complex conjuage (1+4i)

simplify and take the imaginary term

>>

>>7788862

[math] (1-4i)z = 10+11i [/math]

[math] z = \frac{10+11i}{1-4i} [/math]

[math] z = \frac{(10+11i)(1+4i)}{(1-4i)(1+4i)} [/math]

[math] z = \frac{-34}{17} + \frac{51}{17}i = -2 + 3i[/math]

[math] Im(z) = 3i [/math]

Technically, isn't the imaginary part simply 3? Don't we only cite the coefficient of the imaginary unit as the imaginary component of a complex number?
