Assuming 4x + 3 ≥ 0
4x + 3 < 1
4x < - 2
x < -0.5
Assuming 4x + 3 < 0
-(4x + 3) < 1
-4x - 3 < 1
-4x < 4
x > -1

if the inequality is < or > it’s gets parenthesis. If the inequality is <= or >= it gets brackets. Inf and -inf ALWAYS gets parenthesis. Examples: 4<x<6 Int Not: (4,6) bc 4 and 6 are not included 4<= x <= 12 Int Not: [4,12] bc 4 and 12 are included X<5 or x> 14 (-inf, 5) U (14,inf) X<= 7 or x >= 10 (-inf, 7] U [10, inf)
