Given:
The inequality is
To find:
The mistake in the given solution and correct it.
Solution:
We have,
Isolating variable on one side, we get
On dividing both sides by -3, we get
Because if an inequality is multiplied or divided by a negative number, then the sign of inequality must be changed.
Therefore, there is a mistake in last step because the sign of inequality remains same after diving it by -3 and the correct solution is .

Respuesta:
-4;
-1
Explicación paso a paso:
Dado :
-2- | -2 | - | -3 | +3
Los números entre barras verticales son valores absolutos y se tratan como positivos:
-2 - +2 - +3 + 3 = - 2-2-3 + 3 = - 4
| -1 | + | -1 | - | -3 |
Los números entre barras verticales son valores absolutos y se tratan como positivos
1 + 1 - + 3 = 1 + 1-3 = - 1
