Question

Resuelva:

2(x + 2) – 3(5 – x ) = x + 5(x – 3)

A) 5 B) 7 C) 8
D) 4 E)3

Answer 1

Respuesta:

D) 4

Explicación paso a paso:

2(x + 2) – 3(5 – x ) = x + 5(x – 3)

(2x+4) - (15 -3x) = x +5x -15

2x+4 - 15 + 3x = 6x - 15

5x - 11 = 6x - 15

5x - 6x = -15+11

- x = - 4

x = 4

Answer 2

Respuesta:

D) 4

Explicación paso a paso:

2(x + 2) – 3(5 – x ) = x + 5(x – 3)

2x + 4 - 15 + 3x =  x + 5x - 15

2x + 4 + 3x = x + 5x

5x + 4 = x + 5x

5x + 4 = 6x

4 = 6x - 5x

4 = x
