Question : 37

Total: 40

Make

n

y = \; \frac{n-x}{x}

Solution:

Get rid of the fraction by multiplying both sides of the equation by the LCM of the denominators ( 1 and

x

). The LCM is

x

NOTE:

y = \frac{y}{1}

(Every number or letter is being divided by 1)

\Rightarrow y \times x = n - x

Move the

x

at the right to the left in order for

n

to stand alone (the subject)

\Rightarrow y x + x = n

Factorize

x

out at the left side of the equation

\; \Rightarrow x(y+1) = n

\; \Rightarrow n = x(y+1)
