Solve for x: 3 - (2x - 5) < -4(x + 2)
2 answers:
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
Step-by-step explanation:
3-(2x-5) <-4(x+2)
=> 3- 2x +5 +4x +8<0
=> 16 + 2x <0
=> 2x < -16
=> x < -8
