Question

qual o valor da equação seguinte 2x+3x+9=8(6-x)
​

Answer 1

$2x+3x+9=8(6-x)$

$2x + 3x + 9 = 48 - 8x\\\\10x + 3x -39 = 0\\\\13x -39 = 0\\\\13x = 39\\\\x = \frac{39}{13}\\\\x = 3$

Espero ter ajudado

Abraço!

Answer 2

2x+3x+9=8(6-x)

5x + 9 = 48 - 8x

5x + 8x = 48 - 9

13x = 39

x= 39/13

x= 3
