Answer:

(D)
-8x-5=4x+2

Explanation:

The given equation is:


-3x+2-5x-7=4x+2

Combining the like terms, we get


-3x-5x+2-7=4x+2


-8x-5=4x+2

which is the required correct step for solving the given equation.

therefore, again combining the like terms, we get


-8x-4x=2+5


-12x=7


x=(-7)/(12)

thus, option D is correct.
