Question

Resposta da resolução -3(3x-42)=2(7x-52)

Answer 1

$- 3(3x - 42) = 2(7x - 52) \\ \\ - 9x + 126 = 14x - 104 \\ \\ - 9x - 14x = - 104 - 126 \\ \\ - 23x = - 230( - 1) \\ \\ 23x = 230 \\ \\ x = 230 \div 23 \\ \\ x = 10$

Answer 2

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

- 9x + 126 = 14x - 104

- 9x - 14x = - 104 - 126

- 23x = - 230

x= - 230/-23

x= 10
