Urgente!!!!

-3(3x-42)=2 (7x-52)

Pfvr me ajudem!!!!

Answer 1

Resposta:

-3(3x-42)=2 (7x-52)

Faz as distributivas:

-3(3x-42)=2 (7x-52)

-9x + 126 = 14x -104

-9x + 126 = 14x -104

-9x -14x = -104 -126

-23x = -230

x= $\frac{-230}{-23}$

x= 10

Answer 2

-3 (3x - 42) = 2 (7x - 52)

- 9x + 126 = 14x - 104

- 9x - 14x = - 104 - 126

- 23x = - 230

x= - 230/-23

x= 10
