Question

How can you rewrite equations like 2,000 = 20x + 10y to express x as a function of yı? Toexpress y as a function of x?LITNIH

Answer 1

Given : 2,000 = 20x + 10y

To express x as function of y, make the following steps:

20x + 10y = 2000

20x = -10y + 2000

divide all terms by 20

So,

x = -10y/20 + 2000/20

x = -0.5y
