Help!! This doesn't make any sense to me. Can anyone help me solve for the value of x?

Exterior angle of the triangle is equal to the sum of the opposite angles.

9x = 5x + 9 + x

Combine like terms:
9x = 6x + 9

Take away 6x from both sides:
3x = 9

Divide by 3 on both sides:
x = 3

Answer: x = 3

Solve the equation, if possible.

Answer:

no solution

Step-by-step explanation:

Given

- 3 | 6n - 2 | + 5 = 8 ( subtract 5 from both sides )

- 3 | 6n - 2 | = 3 ( divide both sides by - 3 )

| 6n - 2 | = - 1

The absolute value always returns a positive value and so

| 6n - 2 | ≠ - 1

Hence there is no solution to the equation
