Question

5(x-3)=4(x+4) lo saben​

Answer 1

5(x-3) = 4(x+4)

5x − 15 = 4x + 16

5x = 4x + 16 + 15

5x = 4x + 31

5x − 4x = 31

$\boxed{x=31}$

Answer 2

x=31

Explicación paso a paso:

$\boldsymbol{ \texttt{hola}}$

$5(x - 3) = 4(x + 4) \\ 5x - 15 = 4x + 16 \\ 5x - 4x = 16 + 15 \\ x = 31$

$5x(31) - 15 = 4x(31) + 16 \\ 155 - 15 = 124 + 16 \\ 140 = 140$
