Question

if k = y/x and k = 7 and x = 9 calculate y

Answer 1

A value of the variable which, if replaced into an equation, generates a true assertion, and the further calculation can be defined as follows:

Given:

$\bold{k=\frac{y}{x}}\\\\\bold{k=7}\\\\\bold{x=9}$

To find:

y=?

Solution:

$\bold{k=\frac{y}{x}}.....................(i)\\\\\bold{k=7}.......................(ii)\\\\\bold{x=9}...........(iii)$

Putting the equation (ii) and equation (iii) value into the equation (i):

$\to \bold{7=\frac{y}{9}}\\\\\to \bold{y=7\times 9}\\\\\to \bold{y=63}$

Therefore the final value of y is "63".

Answer 2

The value of the $y$  from the expression is $63$.

The given expression is,

$k=\frac{y}{x}$.

The value of $k$ and $x$ is $9$ and $7$.

Substitute $k=7,x=9$ in the expression $k=\frac{y}{x}$ as,

$k=\frac{y}{x}\\7=\frac{y}{9}$

Multiply by $9$ on both sides as,

$7=\frac{y}{9} \\\\7\cdot9 =\frac{y\cdot9}{9}\\y=63$

Therefore, the value of $y$ is $63$.
