here's a question-
some of them might not have an answer but if they don't pls tell me in the comments ^^
1) 9(x + 1) = 9(x - 2)
2) 7x - 3 - 8x = 9 - x - 12
3) 2x -4(x - 1) = 7(x + 6)
4) 5 + 6x - 1 = x + 4 + 5x
5) 2x - 3 = 2x - 3
6) X - 2 + x = 2(x - 1)
7) -(3x + 7) = -2x + 1 - x
8) 7x - 3 - 8x = 9 - 4x + 1
9) 7 + 3x = 12 + 2x
10) -3(-2x - 1) = 4x + 8 + 2x
11) 4x - (x - 10) = 7(2x + 1)

ill give brainly, to whoever answers with correct answers.

Respuesta :

The equations are solved below.

How to compute the equation?

1. 9(x + 1) = 9(x - 2)

9x + 9 = 9x - 18

This doesn't have a solution

2) 7x - 3 - 8x = 9 - x - 12

This doesn't have a solution

3) 2x -4(x - 1) = 7(x + 6)

2x -4x + 1 = 7x + 42

-2x + 1 = 7x + 42

7x + 2x = 1 - 42

9x = -41

x = -41/9

4) 5 + 6x - 1 = x + 4 + 5x

This can't be solved further.

5) 2x - 3 = 2x - 3

This can't be solved further.

6) X - 2 + x = 2(x - 1)

2x - 2 = 2x - 2

This can't be solved further.

7) -(3x + 7) = -2x + 1 - x

-3x - 7 = -3x + 1

This can't be solved further.

8) 7x - 3 - 8x = 9 - 4x + 1

-x - 3 = -4x + 10

-x + 4x = 10 + 3

3x = 13

x = 13/3

9) 7 + 3x = 12 + 2x

3x - 2x = 12 - 7

x = 5

10) -3(-2x - 1) = 4x + 8 + 2x

6x + 3 = 6x + 8

This can't be solved further

11) 4x - (x - 10) = 7(2x + 1)

4x - x + 10 = 14x + 7

3x + 10 = 14x + 7

14x - 3x = 10 - 7

11x = 3

x = 3/11

Therefore, the equations have been solved.
