Find the value of y when x equals 26 x+4y=54
pishuonlain [190]

Factor out the common term "2".

2(13x+2y) = 54

Now, divide both sides by 2.

13x + 2y = 54/2. <-- <u>We could not divide into a whole number so it's a fraction.</u>

<u />

Simplify 54/2 to 27.

13x + 2y = 27 <--- <u>Since we have a whole number without a letter, we are done with that side.</u>

<u />

Now, we subtract 2y from both sides.

13x = 27 - 2y

Divide both sides by 13.

x = 27 - 2y/13.

<h3>Therefore, we get <u>x = 27 - 2y/13</u></h3>

That would be our final answer.

Good luck on your assignment!

Simplify 1/4-7i to get a complex number in standard a + bi form.
Romashka [77]

Answer:

\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i

Step-by-step explanation:

we are given

\frac{1}{4-7i}

Firstly, we will get rid of imaginary term from denominator

so, we will multiply conjugate to both top and bottom term

\frac{1}{4-7i}=\frac{1\times (4+7i)}{(4-7i)\times (4+7i)}

\frac{1}{4-7i}=\frac{4+7i}{4^2-(7i)^2}

\frac{1}{4-7i}=\frac{4+7i}{16+49}

\frac{1}{4-7i}=\frac{4+7i}{65}

we can also write as

so, we get

\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i
