Answer:
D. 
Step-by-step explanation:
First, move the variable (+ 2y) to the left-hand side and change its sign.
Then, move the constant (+ 7) to the right-hand side and change its sign.
Then, collect the like terms (y - 2y)
Finally, add the numbers (3 + 7). That will get you your final answer.
x < -23/2
Step-by-step explanation:
you open the bracket first
LHS
3-(2x - 5)
-6x+15
RHS
-4(x+2)
=-4x-8
therefore:
-6x+15 < -4x-8
By collecting the like terms
-6x+4x < -8-15
=-2x<-23
Divide both side by -2x
-2x/-2 < -23/-2
x < -23/2
