Question

3-4x<x-12,x€{-1,0,1,2,3,4,5,6,7}
can anyone answer​

Answer 1

Answer:

3−4x<x−12

Subtracting 3 from both sides

⟹−3+3−4x<x−12−3

⟹−4x<x−15

Subtracting x from both sides

⟹−4x−x<x−x−15

⟹−5x<−15 ⟹x>3

(Dividing by -5 and reverse the symbols)

As xϵ−1,0,1,2,3,4,5,6,7

The solution set= { 4, 5, 6, 7}
