2(x+3)+3(x+1)=24
Me podríais ayudar porfavor

Answer 1

Hola!

Explicación paso a paso:

$(x - 6).(x - 10) = 60 \\ {x}^{2} -6x - 10x + 60 = 60 \\ {x}^{2} - 16x + 60 = 60 \\ {x}^{2} - 16x = 0 \\ {x}^{2} = 16x \\ x = 16$

$2(x + 3) + 3(x + 1) = 24 \\ 2x + 6 + 3x + 3 = 24 \\ 5x = 24 - 9 \\ 5x = 15 \\ x = 3$
