Respuesta:
a) x = -10
b) x = -4
Explicación paso a paso:
a)
[tex] \mathsf{4(x - 2) + 5 = 2x - 23}[/tex]
[tex] \mathsf{4x - 8 + 5 = 2x - 23}[/tex]
[tex] \mathsf{4x - 3 = 2x - 23}[/tex]
[tex] \mathsf{4x - 3 - 2x = - 23}[/tex]
[tex] \mathsf{4x - 2x = - 23 + 3}[/tex]
[tex] \mathsf{2x = - 23 + 3}[/tex]
[tex] \mathsf{2x = - 20}[/tex]
[tex] \mathsf{x = - 20 \div 2}[/tex]
[tex] \boxed{ \mathsf{x = - 10}}[/tex]
b)
[tex] \mathsf{5(x - 1) + x = 2(x + 4) - 29}[/tex]
[tex] \mathsf{5x - 5 + x = 2x + 8 - 29}[/tex]
[tex] \mathsf{6x - 5 = 2x - 21}[/tex]
[tex] \mathsf{6x - 2x = - 21 + 5}[/tex]
[tex] \mathsf{4x = - 16}[/tex]
[tex] \mathsf{x = - 16 \div 4}[/tex]
[tex] \boxed{ \mathsf{x = - 4}}[/tex]
Espero haberte ayudado ✌️
