Calulations for the following:

-2x-3=2

Book states answer as -5/2. This does not seem to be correct answer.

x/10 + 1.7=-3.5

Book states answer as -52. This also does not seem to be the correct answer

Both answers appear to be correct.

-2x-3=2
-2x - 3 + 3 = 2 + 3
-2x = 5
x = -5/2

If you post your work for the second problem, we'll be glad to correct it.

the book answer is correct

To solve the equations -2x - 3 = 2 and x/10 + 1.7 = -3.5, let's go through the steps to find the correct answers.

1. -2x - 3 = 2:
To solve this equation, follow these steps:

- Start by isolating the term with the variable, which is -2x, by moving the constant term to the other side of the equation. In this case, add 3 to both sides of the equation:
-2x = 2 + 3
-2x = 5

- Next, divide both sides of the equation by -2 to solve for x:
(-2x) / (-2) = 5 / (-2)
This gives us:
x = -5/2

So, the solution to the equation -2x - 3 = 2 is x = -5/2, which agrees with the answer given in the book.

2. x/10 + 1.7 = -3.5:
To solve this equation, follow these steps:

- Start by isolating the term with the variable, which is x/10, by moving the constant term to the other side of the equation. In this case, subtract 1.7 from both sides of the equation:
x/10 = -3.5 - 1.7
x/10 = -5.2

- Next, multiply both sides of the equation by 10 to solve for x:
10 * (x/10) = 10 * (-5.2)
This gives us:
x = -52

So, the solution to the equation x/10 + 1.7 = -3.5 is x = -52, which agrees with the answer given in the book.

Therefore, both of the book's solutions (-5/2 for the first equation and -52 for the second equation) are correct.
