Question

-(3x+7)=x+19 by transposition method​

Answer 1

Step-by-step explanation:

-3x-7=x+19

-3x-x=19+7

-4x=26

-x=26/4

-x=6.5

x=-6.5

Answer 2

Answer:

=> The value of x is $-\frac{13}{2}$

Step-by-step explanation:

Given that:-

$-(3x+7)=x+19$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

=> $-(3x+7)=x+19$

It is written as:

=> $-3x-7=x+19$

Add $7$ on both sides,

=> $-3x-7+7=x+19+7$

Simplifying it further, we get

=> $-3x = x + 26$

Subtract both sides by $x$,

=> $-3x -x= x + 26-x$

=> $-4x = 26$

Divide both sides by $-4$,

=> $x = -\frac{26}{4}$

Canceling the terms, we get

=> $x = -\frac{13}{2}$

Hence, the required solution is $-\frac{13}{2}$.
