Question

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

Answer 1

Answer:

see below

Step-by-step 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)

$2000=20x+10y\\\\2000-10y=20x\\\\x=-\frac{1}{2}x+100$
