Question

solve the following inequation and write the solution set 13X-5<15x+4<7x+12,x€r​

Answer 1

Answer:

-4.5<x<1 or x€(-4.5,1)

Step-by-step explanation:

13X-5<15x+4<7x+12,x€r​

Solving the inequation in pairs:

1. 13x-5<15x+4 => -9<2x=> x>-4.5

2. 15x+4<7x+12 =>8x<8 => x<1

Combining together we get:

-4.5<x<1 or x€(-4.5,1)
