$\huge\boxed{\fcolorbox{pink}{green}{Answer}}$

(ix) 3x/5 - 2x + 1 / 3 > 1

=> 9x - 10x + 5 / 15 > 1

=> -x + 5 / 15 > 1

=> -x + 5 > 15

=> -x > 15 - 5

=> -x > 10

=> x < -10

Therefore, x is real no. is (- infinity, -10)

(x) 2x + 1 / 2 + 2(3 - x) >_ 7

=> 2x + 1 / 2 + 6 - 2x >_ 7

=> 2x + 1 + 12 - 4x / 2 >_ 7

=> -2x + 13 / 2 >_ 7

=> -2x + 13 >_ 14

=> -2x >_ 14 - 13

=> -2x >_ 1

=> x>_ -1/2
