Question

5x-[-2-3x)+4] = -9x -[- (2+4x)-8]+2
alguien me ayuda

Answer 1

Respuesta:

x = 10/7

Explicación paso a paso:

5x - [ -(2 - 3x) + 4] = -9x - [-(2 + 4x) - 8] + 2

5x - [ -2 + 3x + 4] = -9x - [ -2 - 4x - 8] + 2

5x - [ 3x + 2] = -9x - [ -4x - 10] + 2

5x - 3x + 2 = -9x + 4x + 10 +2

2x + 2 = -5x + 12

2x + 5x = 12 - 2

7x = 10

x = 10/7

x ≈ 1.4285714...
