What are the steps to solving for x in this equation? 2x + 6 = - (-8)I'll understand it better if I see it worked step by step

The aim of any equation is to find out the value or values
of the variable that cancel the given expression.


The first
step is to re-write -(-8) = 8. The double negative sign makes a value
positive.


2x + 6 = 8


Now,
we'll subtract 6 both sides in order to isolate the variable x to the left
side:


2x = 8 - 6


2x =
2


Now, we'll divide by 2 and we'll
get:


x = 2/2


x =
1


So, the solution of the equation is x =
1.


We'll verify the solution into equation, substituting
the variable by the value 1:


2*1 + 6 =
8


2 + 6 = 8


8 =
8


So, the solution is x =
1.
