Answer:

x = 9/5 (or x = 1.8 as a decimal).

Explanation:

We can solve for x using the following steps:

Step 1: Distribute -7 to (-x - 1) and -1 to (-2x - 3):

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

-7 + 7x + 7 = 6 + 2x + 3

Step 2: Combine like terms on both sides:

7x = 2x + 9

Step 3: Subtract 2x from both sides:

(7x =2x + 9) - 2x

5x = 9

Step 4: Divide both sides by 5 to solve for x:

(5x = 9) / 5

x = 9/5

Thus, x = 9/5.

If you prefer the decimal answer, x = 1.8.

Optional Step 5: Check the validity of the answer by substituting 9/5 for x and ensuring that you get the same answer on both sides:

-7 - 7(-9/5 - 1) = 6 - (-2(9/5) - 3)

-7 - 7(-14/5) = 6 - (-18/5 - 3)

-7 + 98/5 = 6 - (-33/5)

63/5 = 6 + 33/5

63/5 = 63/5

Thus, our answer is correct.
