What is the result when 1/8x - 2 5/7 is subtracted from 3 1/4x + 7 1/14?

a. 3 1/8x + 9 11/14
b. 3 1/8 + 4 5/14
c.-3 1/8x - 4 5/14
d.-3 1/8x - 9 11/14

3  1/8 X   + 9  11/14

Step-by-step explanation:

I'd suggest you group the x terms together and the constants together separately:

 3  1/4 x  +  7  1/14

-(  [1/8]x    -  2  5/7 )   which becomes;

 3  1/4 x  +  7  1/14

  - [1/8]x    +  2  5/7 )

  3  1/8 X   + 9  11/14     In the column of constants, the LCD is 14.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
