Question

Resuelve a. 5x − 3(1 − 4x) ≤ 4x − 1 b. 5x − 2 x - 3 x - 2 29 ≥ + 3 2 3 6 c. 7(2x − 1) − 3x ≤ 2(x + 1) − 9 d. 3(x − 7) + 2x ≤ 5(x − 1) e. 4(3x − 1) − 5x < 7(x − 1) + 3

Answer 1

a. 5x - 3(1 - 4x) ≤ 4x - 1

5x - 3 + 12x ≤ 4x - 1

13x ≤ 2

x ≤ 2/13

b. 5x - 2x - 3x - 229 ≥ + 3236

-229 ≥ 3236

c. 7(2x - 1) - 3x ≤ 2(x + 1) - 9

14x - 7 - 3x ≤ 2x + 2 -9

9x ≤ 0

x ≤ 0

d. 3(x - 7) + 2x ≤ 5(x - 1)

3x - 21 + 2x ≤ 5x - 5

-21 ≤ -5

e. 4(3x - 1) - 5x < 7(x - 1) + 3

12x - 4 - 5x < 7x - 7 + 3

-4 < -4
