Answer:
-5/2 x -33/4
Step-by-step explanation:
(-11/2 x + 3) -2 (-11/4 x -5/2)
(-11/2 x + 3/1) -2 (-11/4 x -5/2)
The LCM of 2 and 1 is 2, and the LCM of 4 and 2 is 4.
(-11/2 x + 6/2) -2 (-11/4 x -20/4)
( -5/2x) -2 (-31/4)
-5/2x -2 -31/4
-5/2x -2/1 -31/4
LCM of -2 -31/4 is 4
-2/4 -31/4
-33/4
-5/2x -33/4 in simplest form.
