Question

RESOLVA AS INEQUAÇOES:

A)5X-4>3X-10

B)5X-(X-2)<_6( sinal de maior ou igual)

Answer 1

Oi!

a)
5x - 4 > 3x - 10
5x - 3x > - 10 + 4
2x > - 6
x > - 6/2
x > - 3

S = { x ∈ ℝ/ x > - 3}

b)
5x - (x - 2) ≤ 6
5x - x + 2 ≤ 6
4x + 2 ≤ 6
4x ≤ 6 - 2
4x ≤ 4
x ≤ 4/4
x ≤ 1

S = { x ∈ ℝ/ x ≤ 1 }

Bons estudos!
