Question

Saben como hacer esta ecuacion?

Answer 1

Respuesta:

b) 1. x = 4

2. x = 15

3. x = 4

4. x = 22

Explicación paso a paso:

2 ( x + 3 ) = 14

2x + 6 = 14

2x = 14 - 6

2x = 8

x = 8/2

x = 4

3 (x - 6) = 27

3x - 18 = 27

3x = 27 + 18

3x = 45

x = 45/ 3

x = 15

5( x + 1 ) = 25

5x + 5 = 25

5x = 25 - 5

5x = 20

x = 20/5

x = 4

2 ( x - 9 ) + 4 = 30

2x - 18 + 4 = 30

2x -14 = 30

2x = 30 + 14

2x = 44

x = 44/2

x = 22
