Alja [10]3 years ago
5 0

Answer: x = -1; y = -1

y = 3x + 2

y = -2x - 3

⇔ y = 3x + 2

   3x + 2 = -2x - 3

⇔ y = 3x + 2

    5x = -5

⇔ y = 3x + 2

    x = -1

⇔ y = -1

    x = -1

[|(x-4)÷(x+5)|]\leq[4]
Katena32 [7]

Answer:

Solutions are;

x = -8

x = -3.2

Step-by-step explanation:

Here, we want to solve the given equation for x

|(x-4)/(x + 5)| = 4

From what we have, this is an absolute value equation and thus, we are going to have two solutions

These are;

x-4/x+ 5 = 4

x-4 = 4(x + 5)

x-4 = 4x + 20

x-4x = 20 + 4

-3x = 24

x = -24/3

x = -8

secondly;

x-4/x+5 = -4

x-4 = -4(x + 5)

x-4 = -4x - 20

x + 4x = -20 + 4

5x = -16

x = -16/5

x = -3.2
