Question

-2 {-3 [2x-6 (-3x+2)]+2}=12​

Answer 1

Respuesta:

-2 {-3 [2x-6 (-3x+2)]+2} = 12​

$-2-3\left(2x-6\left(-3x+2\right)\right)+2=12\\-3\left(2x-6\left(-3x+2\right)\right)-2+2=12\\-3\left(2x-6\left(-3x+2\right)\right)=12\\\frac{-3\left(2x-6\left(-3x+2\right)\right)}{-3}=\frac{12}{-3}\\-3(2x - 6(-3x + 2) ) = 12\\-3(2x + 18x - 12) = 12\\-3 (20x - 12) =12\\20x - 12 = \frac{12}{-3}\\20x - 12 = -4\\20 x= -4 + 12\\20x = 8\\x = \frac{8}{20}\\\\x = \frac{2}{5}$
