Answer 2

Let's solve the equation step by step:

1. Start with the equation: 5x - 7 + 2x = 3x + 13

2. Combine like terms on both sides of the equation: 7x - 7 = 3x + 13

3. To isolate the variable x on one side of the equation, you can move the 3x from the right side to the left side by subtracting 3x from both sides of the equation: 7x - 3x - 7 = 13

4. Simplify the left side by subtracting 3x from 7x: 4x - 7 = 13

5. Now, add 7 to both sides to isolate 4x: 4x - 7 + 7 = 13 + 7

6. Simplify both sides of the equation: 4x = 20

7. Finally, divide both sides by 4 to solve for x: 4x/4 = 20/4

8. Simplify: x = 5

So, the solution to the equation is x = 5.

Now, let's address the second equation:

1. Start with the equation: 100x + 75 = 50

2. To isolate the variable x, subtract 75 from both sides of the equation: 100x + 75 - 75 = 50 - 75

3. Simplify both sides: 100x = -25

4. Now, divide both sides by 100 to solve for x: 100x/100 = -25/100

5. Simplify: x = -1/4

So, the solution to the second equation is x = -1/4.
