Second, multiple-choice questions (3 points for each question, ***33 points)

1 1。 Divide both sides of the equation -8X=2 by -8 to get (-).

a，X=-4 - B，X= 1/4，......c，X=4.....d，X=- 1/4

12, which of the following transposition is correct (_ _ _).

I from 5+X= 12, x = 5+ 12..........b, 7x = 4x-3, 7X-4X=3.

10x = 1 1 1 1x =-2...d，x-5 = 4x+2。
