Question

Resuelva:
2(x + 2) – 3(5 – x ) = x + 5(x – 3)

Answer 1

Respuesta:

x = 4

Explicación paso a paso:

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

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

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

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

2x -11 + 3x = x + 5x - 15

5x - 11 = x + 5x - 15

5x - 11 = 6x - 15

5x - 6x = -15 + 11

-x = -4

x = 4

Comprobación:

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

2(6) - 3(5 - 4) = 4 + 5(4 - 3)

2(6) - 3(1) = 4 + 5(4 - 3)

2(6) - 3(1) = 4 + 5(1)

12 - 3(1) = 4 + 5(1)

12 - 3 = 4 + 5(1)

12 - 3 = 4 + 5

9 = 4 + 5

9 = 9
