Let's solve for "r" by bringing them all to one side.
-3r=6-4r
+4r +4r
r=6
So, r is equal to 6.

So you have to add the like terms together,

6 - 4r = -3r
+4r +4r

6=1r
Divide 1 to both sides.

6=r

Answer:

see explanation

Step-by-step explanation:

Note the ratios between consecutive terms is constant, that is

- 220 ÷ 11 = 4400 ÷ - 220 = - 88000 ÷ 4400 = - 20

Thus to obtain the next term in the sequence multiply the previous term by - 20

Start with 11 and multiply by - 20

6+2i

aliya0001 [1]

$\frac{6+2i}{3+3i}=\frac{6+2i}{3+3i}\times\frac{3-3i}{3-3i}$
$\frac{6+2i}{3+3i}=\frac{18-18i+6i-6i^{2}}{9-9i+9i-9i^{2}}$
$\frac{6+2i}{3+3i}=\frac{18-12i+6}{9+9}$
$\frac{6+2i}{3+3i}=\frac{24-12i}{18}$
$\frac{6+2i}{3+3i}=\frac{12(2-i)}{18}$
$\frac{6+2i}{3+3i}=\frac{2(2-i)}{3}$
$\frac{6+2i}{3+3i}=\frac{2}{3}(2-i)$
$\frac{6+2i}{3+3i}=\frac{4}{3}-\frac{2i}{3}$
