Determinati nr nat care verifica relatiile a)(x+3)-(130-110)≥37
b)(x+123)-(237-157)>201
c)(67-42)-(x+11)≥0
d)(1 437-1 320)+(250-x)>100
Va rog ajutatima.
a) (x+3) - 20 ≥ 37 x ≥ 54 ⇒ x ∈N \{0,1,2,.....53} b) x + 123 - 237 + 157 > 201 x > 158 ⇒ x ∈ N \ {0,1,2,3.....158} c) 14 - x ≥ 0 x ≤ 14 x ∈ {0,1,2,....14} d) 367 - x > 100 x < 267 ⇒ x ∈ {0,1,2,3........266}
