Question

Determinar o conjunto solução
| 2×-4 |=×-1
| 5×-3 |=2×+7
| ×-4 |= 3×+10
| 2×-10 |=5×+2

Answer 1

| 2x - 4 | = x - 1

2x - 4 = x - 1

2x - x = - 1 + 4

x = 3

=======================

| 5x - 3 | = 2x + 7

5x - 3 = 2x + 7

5x - 2x = 7 - 3

3x = 4

x = 4/3

========================

| x - 4 | = 3x +10

x - 4 = 3x + 10

x - 3 x = 10 + 4

-2x = 14

x = - 14/2

x = - 7

========================

| 2x - 10 | = 5x + 2

2x - 10 = 5x + 2

2x - 5x = 2 + 10

-3x = 12

x = - 12/3

x = - 4
