2x-5x+6x=-392x-5x+6x==39

Answer: x = 0

Step-by-step explanation:

Cancel equal terms on both sides of the equation. 2 x+6 x = 392 x + 6 x or 2 x = - 392 x. move variable to the left handed side and change its sign. 2 x + 392 x = 0. collect like terms 394 x = 0. divide both sides of the equation by 394. x = 0 and your answer is x = 0
