valentina_108 [34]

Answer:

x = - 6

Step-by-step explanation:

Given

4(x + 6) - 2x = 12 ← distribute and simplify left side

4x + 24 - 2x = 12

2x + 24 = 12 ( subtract 24 from both sides )

2x = - 12 ( divide both sides by 2 )

x = - 6

Solve for z, and give your answer in the form a + bi
zzz [600]
The answer is z = 3 + i

z = a + bi
conj(z) = a - bi

conj(7 + 3i) = 7 - 3i

<span>(conj)z + 2z = 2 + 4i + conj(7 + 3i)
</span>a - bi + 2(a + bi) =<span> 2 + 4i + 7 - 3i
</span>a - bi + 2a + 2bi =<span> 2 + 4i + 7 - 3i
</span>3a + bi = 9 + i

From here:
3a = 9        and      bi = i
a = 9/3                   b = i/i
a = 3                       b = 1

z = a + bi
z = 3 + 1 * i
z = 3 + i
