c) x + 1<4
d) x - 2<2

Answer 1

c )

Explanation:

To find equivalent inequalities, we are looking to isolate x on the left side.

a) x < 4 ✅

b) x -1 < 3 add 1 to both sides x -1 +1 < 3 +1 result x < 4 ✅

c) x + 1 < 4 subtract 1 from both sides x + 1 -1 < 4 -1 result x < 3 ❌

d) x - 2 < 2 add 2 to both sides x - 2 +2 < 2+2 result x < 4 ✅
