Answer 2

It looks like you have three equations with a variable "x" that you would like to solve. I'll go through each of them step by step:

Equation 1: 5x = 3x + 8

To solve for x, you can start by subtracting 3x from both sides of the equation:

5x - 3x = 8 2x = 8

Now, divide both sides by 2:

x = 8 / 2 x = 4

So, the solution for Equation 1 is x = 4.

Equation 2: 7x = 5x + 12

Subtract 5x from both sides:

7x - 5x = 12 2x = 12

Divide both sides by 2:

x = 12 / 2 x = 6

The solution for Equation 2 is x = 6.

Equation 3: 3x + 4 = x + 16

Subtract x from both sides:

3x - x + 4 = 16 2x + 4 = 16

Subtract 4 from both sides:

2x = 12

Divide both sides by 2:

x = 12 / 2 x = 6

The solution for Equation 3 is also x = 6.

So, the solutions for the three equations are:

1. x = 4
2. x = 6
3. x = 6
