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!

A line passes through the point (-8,7) and has a
zaharov [31]

Answer:

y = (-5/2)x + 27

Step-by-step explanation:

Use the point slope formula y = mx + b.

Replace m with -5/2, x with -8 and y with 7:

7 = (-5/2)(8) + b.  Find the y-intercept, b:

7 = -20 = b, or b = 27

The equation of this line is y = (-5/2)x + 27.
