2\times 2=7x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of x,2.
4=7x
Multiply 2 and 2 to get 4.
7x=4
Swap sides so that all variable terms are on the left hand side.
x=\frac{4}{7}
Divide both sides by 7.
