Answer 1

Respuesta:

D) x = 6

E) x = 2

F) x = 4

Explicación paso a paso:

D) 4 (x - 1) + 3 (x + 5) = 2x + 41

4x - 4 + 3x + 15 = 2x + 41

4x + 3x - 2x = 41 + 4 - 15

5x = 30

x = 30/5 = 6

E) 12 + 3 (x + 2) = 42 - 3 (x + 4)

12 + 3x + 6 = 42 - 3x - 12

3x + 3x = 42 - 12 - 12 - 6

6x = 12

x = 12/6 = 2

F) 4 (x + 2) = 2x + 16

4x + 8 = 2x + 16

4x - 2x = 16 - 8

2x = 8

x = 8/2 = 4
