Respuesta:

x = 8

Explicación paso a paso:

Simplifying

4x + 9 + 2x + -5 = 8x + 16 + -5x + 12

Reorder the terms:

9 + -5 + 4x + 2x = 8x + 16 + -5x + 12

Combine like terms: 9 + -5 = 4

4 + 4x + 2x = 8x + 16 + -5x + 12

Combine like terms: 4x + 2x = 6x

4 + 6x = 8x + 16 + -5x + 12

Reorder the terms:

4 + 6x = 16 + 12 + 8x + -5x

Combine like terms: 16 + 12 = 28

4 + 6x = 28 + 8x + -5x

Combine like terms: 8x + -5x = 3x

4 + 6x = 28 + 3x

Solving

4 + 6x = 28 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.

4 + 6x + -3x = 28 + 3x + -3x

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

4 + 3x = 28 + 3x + -3x

Combine like terms: 3x + -3x = 0

4 + 3x = 28 + 0

4 + 3x = 28

Add '-4' to each side of the equation.

4 + -4 + 3x = 28 + -4

Combine like terms: 4 + -4 = 0

0 + 3x = 28 + -4

3x = 28 + -4

Combine like terms: 28 + -4 = 24

3x = 24

Divide each side by '3'.

x = 8

Simplifying

x = 8
