Question

Resolva a inequação: 13x + 2(3 – 4x) ≤ 3 – 4(9 + 2x)

Answer 1

13x + 2(3 – 4x) ≤ 3 – 4(9 + 2x)
13x + 6 – 8x ≤ 3 – 36 -8x
5x + 6  ≤ – 33 -8x
5x+8x ≤ -33-6
13x ≤ -39
x ≤ -39/13
x ≤ -3

Answer 2

Olá, boa tarde ☺

Resolução:

13x + 2(3 – 4x) ≤ 3 – 4(9 + 2x)

13x + 6 - 8x ≤ 3 - 36 - 8x

13x - 8x + 8x ≤ 3 - 36 - 6.

13x ≤ -39.

x ≤ -39/13

x ≤ -3.

Bons estudos :)
