Answer 3

1. (x - 17) - 25 = 350

To solve this equation, we can start by simplifying the left side:

x - 17 - 25 = 350

Combine like terms:

x - 42 = 350

Next, isolate the variable by adding 42 to both sides:

x = 350 + 42

x = 392

Therefore, the solution to the equation is x = 392.

2. (x + 42) / 13 = 29

To solve this equation, we can start by isolating the variable. Multiply both sides of the equation by 13:

13 * [(x + 42) / 13] = 29 * 13

Simplify:

x + 42 = 377

Next, isolate the variable by subtracting 42 from both sides:

x = 377 - 42

x = 335

Therefore, the solution to the equation is x = 335.

3. 3(4x - 8) = 120

To solve this equation, we can start by simplifying the left side:

12x - 24 = 120

Next, isolate the variable by adding 24 to both sides:

12x = 120 + 24

12x = 144

Finally, divide both sides by 12 to solve for x:

x = 144 / 12

x = 12

Therefore, the solution to the equation is x = 12.

4. (7x + 2x) / 5 = 63

To solve this equation, we can start by combining like terms:

9x / 5 = 63

Next, isolate the variable by multiplying both sides by 5:

5 * (9x / 5) = 63 * 5

Simplify:

9x = 315

Finally, divide both sides by 9 to solve for x:

x = 315 / 9

x = 35

Therefore, the solution to the equation is x = 35.
