Question

Alguien que el ayude porfaaaaaa

Answer 1

Explicación paso a paso:

Primer problema:

|2x + 1| = 5

2x + 1 = 5

2x + 1 = -5

x = 2

x = -3

x₁ = -3, x₂ = 2

Segundo problema:

|x + 2| = 7x - 10

|x + 2| - 7x = -10

x + 2 - 7x = 10, x + 2 ≥ 0

-(x + 2) - 7x = -10, x + 2 < 0

x = 2, x ≥ - 2

x = 1, x < -2

x = 2

x ∈ ∅

x = 2

Tercer problema:

|3x + 1| = x + 5

|3x + 1| - x = 5

3x + 1 - x = 5, 3x + 1 ≥ 0

-(3x + 1) - x = 5, 3x + 1 < 0

x = 2, x ≥ -1/3

x = -3/2, x < -1/3

x = 2

x = -3/2

x₁ = -3/5, x₂ = 2
