Y = (3) / (10-x) Solve for x.

Work: Y=3 / (10-x)

Solve for x

* (10-x) both sides

Y (10-x) = 3

10y-xy=3

-10y both sides

-xy=-10y+3

:-y both sides

X = (10y-3) / y

Simplify

X=10y/y-3/y

X=10-3/y

Answer: x=10-3/y

Check your work: plug in x

Y=3 / (10 - (10-3/y))

Simplify

Y=3 / (10-10+3/y)

Y=3 / (3/y)

Y=3*y/3

Y=y

The answer is correct
