4х - 16 = 6 * (3 + х)
4х - 16 = 18 + 6х
4х - 6х = 18 + 16
- 2х = 34
х = 34 : (- 2)
х = - 17
-------------------------------------------
4 * (- 17) - 16 = 6 * (3 + (- 17))
- 68 - 16 = 6 * (- 14)
- 84 = - 84

4x - 16 = 6(3 + x)

Simplify.

4x - 16 = 18 + 6x

Add 16 to both sides.

4x = 18 + 6x + 16

Subtract 6x from both sides.

4x - 6x = 18 + 16

Simplify.

-2x = 34

Divide both sides by -2.

x = -17

~Hope I helped!~
