Question

Solve 8x+9=3(x-1)+7​

Answer 1

Answer:

-1

Step-by-step explanation:

8x+9=3x-3+7

8x+9=3x+4

5x= -5

x= -1

Answer 2

Answer:

=> The value of x is -1.

Step-by-step explanation:

Given that:-

$8x+9=3(x-1)+7$

To find: - The expression's value:

In this case, we'll apply the transposition method.

First, we must identify the variables and constants.

Then, using various mathematical operations, solve the expressions on both sides.

As we have, 

=> $8x+9=3(x-1)+7$

Distributing the terms, we get

=> $8x+9=3x-3+7$

Simplifying it further, we get

=> $8x+9=3x+4$

Now subtract both sides by $9$,

=> $8x+9-9=3x+4-9$

=> $8x = 3x-5$

Again subtract both sides by $3x$,

=> $8x -3x= 3x-5-3x$

=> $5x = -5$

Divide both sides by $5$,

=> $x = -1$

Hence, the required solution is -1.
