Answer:

x = 6

Step-by-step explanation:

5x - 10 = 2 - 2x + 10(x - 3)

=> 5x - 10 = 2 - 2x + 10x - (10 × 3)

=> 5x - 10 = 2 - 2x + 10x - 30

=> 5x - 10 = 2 + 8x - 30

=> 5x - 10 = 8x - 28

=> 28 - 10 = 8x - 5x

=> 18 = 3x

=> 18/3 = x

=> 6 = x

Answer:

A

Step-by-step explanation:

5x - 10 = 2 - 2x + 10(x - 3) ← distribute parenthesis and simplify right side

5x - 10 = 2 - 2x + 10x - 30

5x - 10 = 8x - 28 ( subtract 8x from both sides )

- 3x - 10 = - 28 ( add 10 to both sides )

- 3x = - 18 ( divide both sides by - 3)

x = 6
