Question

71 + [+5x + (-2x+3)] = 25 - [- (3x+4) - (4x+3)]

Answer 1

Respuesta:

21/2 = x

Explicación paso a paso:

71 + [+5x + (-2x+3)] = 25 - [- (3x+4) - (4x+3)]

71 + [5x - 2x+3] = 25 - [- 3x - 4 - 4x - 3]

71 + 3x + 3 = 25 + 7x + 7

74 + 3x = 32 + 7x

74 -32 = 7x  - 3x

42 = 4x

42/4 = x

21/2 = x
