Answer 2

Answer:

=> Hence, the value of x is -9.

Step-by-step explanation:

In context to questions asked,

We have to determine the value of x,

Here we will use the transposition method.

The given expression,

$8x+9=7x$

Now, subtract both sides by $9$:

=> $8x+9-9=7x-9$

=> $8x=7x-9$

Subtract $7x$ on both sides by,

=> $8x-7x=7x-9-7x$

=> $1x = -9$

Multiply both sides by $1$,

=> $x = -9$
