Question

1. -2x + 8 = 2x + 42. 3x + 7 - 2x = 4x + 103. 4x + 8 = 3(x - 1) + 124. 7x - 2 = 9x + 10​

Answer 1

Answer:

4. $\displaystyle -6 = x$

3. $\displaystyle 1 = x$

2. $\displaystyle -1 = x$

1. $\displaystyle 1 = x$

Step-by-step explanation:

4. 7x - 2 = 9x + 10

- 9x + 2 - 9x + 2

_____________

$\displaystyle \frac{12}{-2} = \frac{-2x}{-2} \\ \\ -6 = x$

3. 4x + 8 = 3(x - 1) + 12

4x + 8 = 3x - 3 + 12

4x + 8 = 3x + 9

- 4x - 9 - 4x - 9

____________

$\displaystyle \frac{-1}{-1} = \frac{-x}{-1} \\ \\ 1 = x$

2. 3x + 7 - 2x = 4x + 10

x + 7 = 4x + 10

- 4x - 7 - 4x - 7

____________

$\displaystyle \frac{3}{-3} = \frac{-3x}{-3} \\ \\ -1 = x$

1. −2x + 8 = 2x + 4

- 2x - 8 - 2x - 8

____________

$\displaystyle \frac{-4}{-4} = \frac{-4x}{-4} \\ \\ 1 = x$
