Solve the equation 3x + 6y = 18 for x.

Elena-2011 [213]

3x + 6y = 18 -6y

3x = 18 - 6y Divide by 3

3x/3=18/3-6y/3 Simplify

x=6-2y

Now we check by plugging in the value of x.

3(6-2y)+6y=18 simplify

18-6y+6y=18 simplify more

18=18.

NOW we know for sure that this is correct

x=6-2y

Subject to some of (3/5 + 1/5i) and (4/5 - 2/5i) from (9/5 - 1/5i). the result is what

romanna [79]

The correct answer is: 2/5.

Explanation:

First you have to add the following expressions:

$(\frac{3}{5}+\frac{1}{5}i)+(\frac{4}{5}-\frac{2}{5}i) \\ (\frac{3}{5}+ \frac{4}{5})+(\frac{1}{5}i-\frac{2}{5}i) \\= \frac{7}{5}-\frac{1}{5}i$

Now subtract the above expression from $(\frac{9}{5}-\frac{1}{5}i)$ :

$(\frac{9}{5}- \frac{1}{5}i) - (\frac{7}{5} -\frac{1}{5}i) \\ (\frac{9}{5} -\frac{7}{5}) + (\frac{1}{5}i -\frac{1}{5}i) \\ \frac{2}{5} \\$

Hence the correct answer is 2/5.

Assignment due today Q-Q<br> 9 1/2=k/9

$\huge\mathfrak\blue{answer}$

$= q - \frac{q91}{2} = \frac{k}{9}$

$\blue{switch \: sides}$

$= \frac{k}{9} = q - \frac{q91}{2}$

$\blue{multiply \: 9 \: both \: sides}$

$= \frac{9k}{9} = 9q - 9 \: . \: \frac{q91}{2}$

$\blue{lastly \: simplify}$

$=\underline {k = 9q - \frac{{9q}^{91} }{2} }$
