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.
