Question

|4x+3|-4=0 допоможіть

Answer 1

Ответ:

-1.75 и 0.25

Объяснение:

$|4x + 3| - 4 = 0$

$|4x + 3| = 4 \\ 4x + 3 = 4 \\ 4x = 4 - 3 \\ 4x = 1 \\ x = 1 \div 4 \\ x = 0.25$

$4x + 3 = - 4 \\ 4x = - 4 - 3 \\ 4x = - 7 \\ x = - 7 \div 4 \\ x = - 1.75$

Answer 2

Решение и ответ:

|4x + 3| - 4 = 0

|4x + 3| = 4

1) 4x + 3 = 4

  4x = 4 - 3

  4x = 1

  x = 1 ÷ 4

  x₁ = 0.25

2) 4x + 3 = -4

   4x = -4 - 3

   4x = -7

   x = -7 ÷ 4

   x₂ = -1.75
