Question

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

express y as a function of x?

Answer 1

see below

Explanation:

to express x as a function of y we need to form this

`y=mx+b`

and to express y as a function of x

`x=ay+c`

so we work

1)

`2000=20x+10y\\\\2000-20x=10y\\\\y=-2x+200`

2)

`2000=20x+10y\\\\2000-10y=20x\\\\x=-(1)/(2)x+100`
