i) {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}
ii) {-2 , -1 , 0 , 1}
iii) {-1 , 0 , 1 ,2 , 3 , 4 , 5}
i) 7 - x > 0
⇔ 7 > x
⇔ x < 7
⇔ x ∈ {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

ii) 3 - 4x > -2
⇔ 3 + 2 > 4x
⇔ x < 5/4
⇔ x ∈ {-2 , -1 , 0 , 1}
iii) 3x + 4 > -2
⇔ 3x > -2 - 4
⇔ 3x > -6
⇔ x > -6/3
⇔ x > -2
⇔ x ∈ {-1 , 0 , 1 ,2 , 3 , 4 , 5}
