​

Answer 1

Step-by-step explanation:

Fermentation is the process in which a substance breaks down into a simpler substance. Microorganisms like yeast and bacteria usually play a role in the fermentation process, creating beer, wine, bread, kimchi, yogurt and other foods.

Answer 2

Answer:

Step-by-step explanation:

// Solve equation [2] for the variable  x  

 

[2]    4x = 5y - 3

[2]    x = 5y/4 - 3/4

// Plug this in for variable  x  in equation [1]

 [1]    3•(5y/4-3/4) + 5y = -11

 [1]    35y/4 = -35/4

 [1]    35y = -35

// Solve equation [1] for the variable  y  

 [1]    35y = - 35  

 [1]    y = - 1  

// By now we know this much :

  x = 5y/4-3/4

  y = -1

// Use the  y  value to solve for  x  

  x = (5/4)(-1)-3/4 = -2
