Answer 2

To solve these equations, let's take them one by one:

1. -12 = 3x

To solve for x, divide both sides of the equation by 3: -12/3 = 3x/3 -4 = x Therefore, the solution is x = -4.

2. 4x + 45 + x = 0

Combine like terms on the left side of the equation: 5x + 45 = 0

To isolate x, subtract 45 from both sides: 5x = -45

Divide both sides by 5: x = -45/5 x = -9 Therefore, the solution is x = -9.

3. 10x - 38 = 25 + x

To solve for x, let's simplify the equation first: 10x - x = 25 + 38 9x = 63

Divide both sides by 9: x = 63/9 x = 7 Therefore, the solution is x = 7.

4. 67 = 13x + 19 - 7x

Combine like terms on the right side: 67 = 6x + 19

Subtract 19 from both sides: 67 - 19 = 6x 48 = 6x

Divide both sides by 6: x = 48/6 x = 8 Therefore, the solution is x = 8.

Summary of solutions:

1. x = -4
2. x = -9
3. x = 7
4. x = 8
