Answer 1

Respuesta:

$x + 24 = 56 \\ x = 56 - 24 \\ x = 32$

$x + 2 = 6 \\ x = 6 - 2 \\ x = 4$

$x + 5 = 103 \\ x = 103 - 5 \\ x = 98$

$x + 36 = 256 \\ x = 256 - 36 \\ x = 220$

$x + 23 = 698 \\ x = 698 - 23 \\ x = 675$

$x - 12 = 546 \\ x = 546 + 12 \\ x = 558$

$x - 96 = 359 \\ x = 359 + 96 \\ x = 455$

$x - 593 = 193 \\ x = 193 + 593 \\ x = 786$

$x - 12.5 = - 10.8 \\ x = - 10.8 + 12.5 \\ x = 1.7$

$x - 53.89 = - 60 \\ x = - 60 + 53.89 \\ x = - 6.11$

$3 + x = 13 \\ x = 13 - 3 \\ x = 10$

$15 + x = 69.5 \\ x = 69.5 - 15 \\ x = 54.5$

$362 - x = 46 \\ - x = 46 - 362 \\ - x = - 316 \\ x = 316$

$1568 - x = 568 \\ - x = 568 - 1568 \\ - x = - 1000 \\ x = 1000$

$23.5 - x = 50 \\ - x = 50 - 23.5 \\ - x = 26.5 \\ x = 26.5$

Para verificar que estén correctas solo tienes que sustituir la x por el valor correspondiente.
