Answer 2

$\sf\huge\bold{Answer:}$

Given :

3.8x+9.2=2.7x-6.2

To find :

Value of x

Solution :

$\implies3.8x+9.2=2.7x-6.2$

Step 1 : Simplifying equation by bringing constant terms on one side and variable terms to other side.

$\implies3.8x - 2.7x = -6.2 - 9.2$

$\implies1.1x = - 15.4$

Step 2 : Solving the equation by dividing -15.4 with 1.1

$\implies \: x = - \frac{15.4}{1.1}$

$\implies \: x = - 14$
