please mark me as brainlist

Step-by-step explanation:

Given equation is 2x−(

3

1

)=(

5

1

)−x

To find out: The value of x

Transporting the constant term to RHS and the variable x to the LHS, we get:

2x+x=(

5

1

)+(

3

1

)

⇒3x=(

15

3+5

)

⇒3x=(

15

8

)

⇒x=(

45

8

)

∴ x=

45

8

is the solution of the given equation.

Let us now substitute the value of x in the equation to verify the solution.

(i) Substituting the value on LHS:

2×

45

8

−(

3

1

)

⇒

45

16

−

3

1

⇒

45

16−15

⇒

45

1

....(1)

(ii) Substituting the value on RHS:

5

1

−

45

8

⇒

45

9−8

⇒

45

1

....(2)

From (1) and (2), we get, LHS = RHS.

Hence, it is verified that the obtained solution is correct.
