Answer 2

Answer:

Given:-

$\dfrac{3}{- 5} = \dfrac{x}{15}$, value of "x" is?

To Find:-

The value of "x".

Note:-

●》Here, we will find the value of "x" by transposing the terms.

●》For finding variables, constant needs to transposed from its side to another and signs are also changed or not. For example - Multiple becomes divisional ( signs are not changed ).

●》Equation means two side term calculations should be equal i.e. L.H.S = R.H.S

Solution:-

$\huge\red{ \dfrac{3}{- 5} = \dfrac{x}{15}}$

$\huge\red{\ \ \ \ x = ?}$

☆ According to note first and second point~

▪︎$\dfrac{3}{- 5} = \dfrac{x}{15}$

▪︎$\dfrac{3}{- 5} × 15 = x$

▪︎$3 × - 3 = x$

☆ After doing multiplication~

▪︎$- 9 = x$

$\huge\pink{x = - 9}$

Checking:-

♤ Let's check accordingly to note third point~

• $\dfrac{3}{- 5} = \dfrac{x}{15} \ \ ?$

• $\dfrac{3}{- 5} = \dfrac{- 9}{15} \ \ ?$

• $\dfrac{3}{- 5} = \dfrac{- 3}{5} \ \ ?$

♤ As it does not matter that negative signs are in denominators or numerators~

• $- \ \dfrac{3}{5} = - \ \dfrac{3}{5} \ \ ?$

♤ Yes!

$\huge\green{Hence,Proved : x = - 9}$

Answer:-

Hence, the value of x = - 9.
