Question

7|x-2|-7=-2|x-2| + 11

Answer 1

Explicación paso a paso:

$7 |x - 2| - 7 = - 2 |x - 2| + 11 \\ \\ 7 |x - 2| - 7+ 2 |x - 2| - 11 = 0 \\ \\ 9 |x - 2| - 18 = 0 \\ \\ 9( |x - 2| - 2) = 0 \\ \\ |x - 2| - 2 = 0 \\ \\ |x - 2| = 2 \\ \\ x - 2 = \pm2 \\ \\ x = \pm2 + 2 \\ \\ x_{1} = 4 \\ x_{2} = 0$
