Answer 2

Answer:

=> The value of x is -10.

Step-by-step explanation:

Given that:-

$\frac{7x}{5} =x - 4$

To find:- The value of the expression,

To find the value of x, we must follow the transposition method:

As we have,

=> $\frac{7x}{5} =x - 4$

Subtract $x$ from both sides,

=> $\frac{7x}{5} -x=x - 4-x$

=> $\frac{7x}{5} -\frac{5(-x)}{5} =x - 4-x$

Simplifying it further, we get

=> $\frac{7x+5(-x)}{5} =x - 4-x$

=> $\frac{7x-5x}{5} =x - 4-x$

=> $\frac{2x}{5} = - 4$

Now multiply both sides by $5$,

=> $\frac{2x}{5}\times 5 = - 4\times 5$

=> $2x = -20$

Divide both sides by $2$,

=> $x = -10$

Hence, the required solution is -10.
