Answer 1

Answer:

x = -1

Step-by-step explanation:

13x + 7 = -9 - 3x

13x + 3x = -9 - 7

16x = -16

x = -16/16

therefore x = -1

Answer 2

Answer:

=> x = -1

Step-by-step explanation:

Given that,

$13 x + 7 = - 9 - 3x$

To find:- The value of the expression:

Here we will use the transposition method.

As we have,

=> $13 x + 7 = - 9 - 3x$

Now, rearrange the terms:

=> $13 x + 7 = - 3x- 9$

Subtract both sides by $7$, we get

=> $13 x + 7-7 = - 3x- 9-7$

=> $13 x = - 3x- 9-7$

=> $13 x = - 3x- 16$

Add $3x$ on both sides, we get

=> $13 x+3x = - 3x- 16+3x$

=> $16x =-16$

Divide both sides, we get

=> $x = -1$

Hence, the required solution is -1.
