Question

plz friends........ help me....... solve the following inequation and write the solution set. 13x-5<15x+4<7x+12, x£R

Answer 1

Answer:

Step-by-step explanation:

The given inequality is:

$13x-5<15x+4<7x+12$

which gives rise to two cases that are:

Case 1:$15x+4>13x-5$

Case2:$15x+4<7x+12$

Solving the case 1, we have

$15x+4>13x-5$

$15x-13x>-5-4$

$2x>-9$

$x>\frac{-9}{2}$

Solving the case 2, we get

$15x+4<7x+12$

$15x-7x<12-4$

$8x<8$

$x<1$

therefore, x∈($\frac{-9}{2},1$)

Answer 2

Answer:

x €(-9/2,1)

Step-by-step explanation:

x€(-9/2,1)
