Question

Solve for x: 3 - (2x - 5) < -4(x + 2)

Answer 1

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

Answer 2

Step-by-step explanation:

3-(2x-5) <-4(x+2)

=> 3- 2x +5 +4x +8<0

=> 16 + 2x <0

=> 2x < -16

=> x < -8
