Question

(5x-3) por (x+4)
aiuda​

Answer 1

Respuesta:

5x - 3 ( x - 4 ) = 4 ( x+2 ) + 2 ( 9-2x )

5x - 3X+12= 4x + 8 +18 -4x

5X - 3x+12=4x - 4x + 26

5X - 3X = 26 - 12

2X = 14

X = 14 / 2

X = 7.

Answer 2

Respuesta:

$5 \times - 3( \times - 4) = \\ 4( \times + 2) + 2(9 - 2 \times ) \\ 5 \times - 3 \times + 12 = 4 \times + 8 + 18 - 4 \times \\ 5 \times - 3 \times + 12 = 4 \times - 4 \times + 26 \\ 5 \times - 3 \times = 26 - 12 \\ 2 \times = 14 \\ \times = 14 |2 \\ \times = 7$
