Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of basic mathematics will help to get the value of $x$ .Finding an equation's solutions, which are values that satisfy the condition given by the equation and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution.

Given:

The given equation is $0.3(6+x)=0.4(8-x)$

To Find:

We need to find the value of $x$ from the equation which is $0.3(6+x)=0.4(8-x)$.

Solution:

The equation is to solve is $0.3(6+x)=0.4(8-x)$

We have solve this equation.

$0.3(6+x)=0.4(8-x)$ can be written as $1.8+0.3x=3.2-0.4x$

Take all the $x$ in the L.H.S of the equation.

Then the equation will be $0.3x+0.4x=3.2-1.8$

From the above equation We will get $0.7x=1.4$

The value of $x$ is $x=\frac{1.4}{0.7}=2$

(By eleminating the point we will divide $14$ by $7$ )

The final answer is $2$ .
