Question

If(8-10x)-(13x-2)= -9 then the value of x is?

Answer 1

Answer:

x = 19 / 23     Decimal value = 0.826

Step-by-step explanation:

Given :

( 8 - 10 x ) - ( 13 x - 2 ) = - 9

We have to find value of x .

First remove the bracket.

8 - 10 x - 13 x + 2 = - 9

Now transfer variable one side and constant one side.

8 + 2 + 9 = 10 x + 13 x

Now do basic addition here

23 x = 19

x = 19 / 23

x = 0.826

Verification:

( 8 - 10 x ) - ( 13 x - 2 ) = - 9

putting x = 19 / 23.

L.H.S. = 8 - 10 x - 13 x +2

L.H.S. = 10 - 23 x

L.H.S. = 10 - 23 × ( 19 /23 )

L.H.S. = 10 - 19

L.H.S. =  -9

L.H.S. = R.H.S.

Hence verified.
