$Hola$

$Tema : Ecuaciones$

$Ejercicio \: 1:$

$4(x + 3) + 5 = 25$

$4x + 12 + 5 = 25$

$4x + 17 = 25$

$4x = 25 - 17$

$4x = 8$

$x = 8 \div 4$

$x = 2$

$Ejercicio \: 2$

$14 + 3(x + 4) = 2$

$14 + 3x + 12 = 2$

$26 + 3x = 2$

$3x = 2 - 26$

$3x = - 24$

$x = - 24 \div 3$

$x = - 8$

Answer 2

a)

$4(x + 3) + 5 = 25 \\ 4x + 12 + 5 = 25 \\ 4x = 25 - 5 - 12 \\ 4x = 8 \\ x = 8 \div 4 \\ x = 2$

b)

$14 + 3(x + 4) = 2 \\ 14 + 3x + 12 = 2 \\ 3x = 2 - 12 - 14 \\ 3x = - 24 \\ x = - 24 \div 3 \\ x = - 8$
