Solve and explain the equation 2x + 16 = 10

In order to solve the equation, we'll have to find a value
for x so that the equation to hold, even after the substitution of the unknown x with
the found value was made.

A proper manner to solve this
type of equation would be  to subtract, both sides of the equation, the opposite value
of the one of the left side, so that, in the end, the left side to contain only the
unknown
x.

2x+16-16=10-16

2x=-6

Now,
to move 2 across the equal sign, we need to divide both sides of the equation with
2.

2x/2=-6/2

x=-3
