(i) y+10 x=x y Apply transposition to make y as the subject. (ii) Given, &gamma;+10 x=x y, make y as the subject. (iii) Collect the terms involving &gamma; and write on LHS and write the remaining terms on RHS.

Q. If the sum of $y$ and ten times $x$ is equal to the product of $x$ and $y$ , then give the formula with $y$ as the subject.

$y = \frac{10 x}{x - 1}$

$y = \frac{10 x}{1 - x}$

$y = \frac{10 x}{x + 1}$

$y = \frac{10}{1 - x}$

(i) $y + 10 x = x y$
Apply transposition to make $y$ as the subject.
(ii) Given, $γ + 10 x = x y$ , make $y$ as the subject.
(iii) Collect the terms involving $γ$ and write on LHS and write the remaining terms on RHS.

Q. If the sum of y and ten times x is equal to the product of x and y, then give the formula with y as the subject.

y=x−110x​

y=1−x10x​

y=x+110x​

y=1−x10​
