Answer 2

Let's solve the equations one by one:

1. 878 - (457 + x) = 239

First, simplify the equation by combining like terms within parentheses:

878 - 457 - x = 239

Now, subtract 457 from 878:

421 - x = 239

Next, isolate x by subtracting 421 from both sides:

-x = 239 - 421

Simplify the right side of the equation:

-x = -182

To solve for x, multiply both sides of the equation by -1:

x = 182

Therefore, the solution to the equation is x = 182.

2. 7(123 - 4x) / 749

To solve this equation, perform the multiplication first:

861 - 28x / 749

There is no equal sign (=) in this equation. If you meant to solve for something specific or if there is an equation missing, please provide more information.

3. 32 - (x + 1) = 1

Simplify the equation by removing the parentheses:

32 - x - 1 = 1

Combine like terms:

31 - x = 1

To isolate x, subtract 31 from both sides:

-x = 1 - 31

Simplify the right side:

-x = -30

Multiply both sides by -1:

x = 30

The solution to the equation is x = 30.

4. (57 - x) - 41.2 = 6.286

Start by simplifying the equation:

57 - x - 41.2 = 6.286

Combine like terms:

15.8 - x = 6.286

To isolate x, subtract 15.8 from both sides:

-x = 6.286 - 15.8

Simplify the right side:

-x = -9.514

Multiply both sides by -1:

x = 9.514

The solution to the equation is x = 9.514.

5. (7.2 + x) = 4.2 * 30.996

Start by simplifying the right side:

7.2 + x = 125.9872

Next, isolate x by subtracting 7.2 from both sides:

x = 125.9872 - 7.2

Simplify:

x = 118.7872

The solution to the equation is x = 118.7872.
