Respuesta:
a) x = 2 b) x = 3
c) x = 43
3. C) 3
Explicación paso a paso:
a) 5(x + 8) = 50 b) 2(x - 5) + 3(x + 5) = 20
5x + 40 = 50 2x - 10 + 3x + 15 = 20
5x = 50 - 40 5x + 5 = 20
5x = 10 5x = 20 - 5
x = 10/5 5x = 15
x = 2 x = 15/5
x = 3
c) [tex]\frac{3(x-8)}{5} = 21[/tex]
[tex]\frac{3x - 24}{5} = 21[/tex]
3x - 24 = 5(21)
3x = 105 + 24
3x = 129
x = 129/3
x = 43
3. 3(x + 5) = 2(x + 18)
3x + 15 = 2x + 18
3x - 2x = 18 - 15
C) 3
Listo, espero haberte ayudado y dame coronita pls
y tambien se mi n ov ia uwun't
