Answer 1

${\huge{\bold{\underline{Answer:-}}}}$

]Given : 13x−5<15x+4<7x+12

⇒   15x+4>13x−5 and 15x+4<7x+12

⇒   15x−13x>−5−4⇒15x−7x<12−4

⇒   2x>−9⇒8x<8

⇒   x>2−9⇒x<1

Solution : {x:2−9<x<1,x∈R}

Answer 2

Answer:

]Given : 13x−5<15x+4<7x+12

⇒ 15x+4>13x−5 and 15x+4<7x+12

⇒ 15x−13x>−5−4⇒15x−7x<12−4

⇒ 2x>−9⇒8x<8

⇒ x>2−9⇒x<1

Solution : {x:2−9<x<1,x∈R}
