Answer 2

To solve these equations, let's perform the necessary steps one by one:

1. 3x - 12 = 2x + 15

To solve for x, we need to isolate the variable on one side of the equation. Let's start by moving all the x terms to the left side and the constants to the right side:

3x - 2x = 15 + 12

Simplify the equation:

x = 27

So the solution for the first equation is x = 27.

2. -4x + 14 = 2x + 15

Similar to the previous equation, let's isolate the x term on one side:

-4x - 2x = 15 - 14

Simplify:

-6x = 1

Now, divide both sides by -6 to find the value of x:

x = -1/6

The solution for the second equation is x = -1/6.

3. -3x + 13 = -4x + 6

Again, let's isolate the x term:

-3x + 4x = 6 - 13

Simplify:

x = -7

The solution for the third equation is x = -7.

4. 5x - 19 = 8x - 4

Isolate the x term:

5x - 8x = -4 + 19

Simplify:

-3x = 15

Now, divide both sides by -3 to find the value of x:

x = -5

The solution for the fourth equation is x = -5.

To summarize:

1. x = 27
2. x = -1/6
3. x = -7
4. x = -5
