Question

Resolva a equação do 1 grau:
a-)-3(3x-42)=2(7x-52)

Answer 1

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

- 9x + 126 = 14x - 104

- 9x - 14x = - 104 - 126

- 23x = - 230

$\frac{-230}{-23} = 10$

x = 10

Answer 2

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


$- 9x + 126 = 14x - 104$


$- 9x - 14x = - 104 - 126$


$- 23x = - 230$


$23x = 230$


$x = 230 \div 23$


$x = 10$
