Answer:
Step-by-step explanation:
Proportional functions can be written as 
, where 
is some constant of proportional. Since directly proportional functions always pass through the origin, the y-intercept must be 0 (no additional number before or after 
term). The only answers that fit this format are:
<span>8x-27-10-6x=15
2x-37=15
2x=15+37
2x= 52
x=26</span>
To solve this, follow these steps:
5x + 27 = 9 (x+3) - 4x
Distribute the 9 within the parenthesis:
5x + 27 = 9x + 27 - 4x
Then combine like terms:
5x + 27 = 5x + 27
These two then cancel each other out completely.
This is an identity because an identity in math is when both equations equal each other, which is shown above.
Hope this helps!
