Respuesta:

$x + 9 = 23 \\ x = 23 - 9 \\ x = 14$

$x + 8 = 15 \\ x = 15 - 8 \\ x = 7$

$x + 11 = 47 \\ x = 47 - 11 \\ x = 36$

$5x + 12 = 47 \\ 5x = 47 - 12 \\ 5x = 35 \\ x = 35 \div 5 \\ x = 7$

$x - 3 = 7 \\ x = 7 + 3 \\ x = 10$

$x + 39 = 50 \\ x = 50 - 39 \\ x = 11$

$x + 57 = 71 \\ x = 71 - 57 \\ x = 14$

$x + 3 = 16 \\ x = 16 - 3 \\ x = 13$

$20 + x = 25 + 4 \\ x = 29 - 20 \\ x = 9$

$24 + x = 46 - 13 \\ x = 33 - 24 \\ x = 9$

$4x + 12 = 3x \\4x + 3x = 12 \\ 7x = 12 \\ x = 12 \div 7 \\ x = 1.7 = 2$

$7 + 24 = x + 12 \\ 31 = x + 12 \\ 31 - 12 = x \\ 19 = x$
