No entiendo esto. Es el tema de Inecuaciones y es con gráfico. 2 < 5 - 3x < 14.

En resumen

Simplifying 5 + - 3x = 14 + 6x Solving 5 + - 3x = 14 + 6x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add ' - 6x' to each side of the equation.

Simplifying

5 + - 3x = 14 + 6x

Solving

5 + - 3x = 14 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add ' - 6x' to each side of the equation.

5 + - 3x + - 6x = 14 + 6x + - 6x

Combine like terms : - 3x + - 6x = - 9x

5 + - 9x = 14 + 6x + - 6x

Combine like terms : 6x + - 6x = 0

5 + - 9x = 14 + 0

5 + - 9x = 14

Add ' - 5' to each side of the equation.

5 + - 5 + - 9x = 14 + - 5

Combine like terms : 5 + - 5 = 0

0 + - 9x = 14 + - 5 - 9x = 14 + - 5

Combine like terms : 14 + - 5 = 9 - 9x = 9

Divide each side by ' - 9'.

X = - 1

Simplifying

x = - 1.
