0\times 7071=0\times 6198x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
0=0\times 6198x
Multiply 0 and 7071 to get 0.
0=0x
Multiply 0 and 6198 to get 0.
0=0
Anything times zero gives zero.
\text{true}
Compare 0 and 0.
x\in \mathrm{R}
This is true for any x.
x\in \mathrm{R}\setminus 0
Variable x cannot be equal to 0.
