Answer:
x = - 10
Step-by-step explanation:
The initial expression is:
x + x + 2 + x + 4 + x + 6 = - 28
So, we can reorganize the terms and add the like terms:
(x + x + x + x) + (2 + 4 + 6) = - 28
4x + 12 = - 28
Then, we can subtract 12 from both sides:
4x + 12 - 12 = - 28 - 12
4x = - 40
Finally, divide both sides by 4:
4x/4 = - 40/4
x = - 10
So, the solution of the equation is x = - 10
