a+2=2+2a\times \frac{1}{2}
Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2a, the least common multiple of 2a,a,2.
a+2=2+a
Multiply 2 and \frac{1}{2} to get 1.
a+2-a=2
Subtract a from both sides.
2=2
Combine a and -a to get 0.
\text{true}
Compare 2 and 2.
a\in \mathrm{R}
This is true for any a.
a\in \mathrm{R}\setminus 0
Variable a cannot be equal to 0.
