2\times 28=7x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 6x, the least common multiple of 3x,6.
56=7x
Multiply 2 and 28 to get 56.
7x=56
Swap sides so that all variable terms are on the left hand side.
x=\frac{56}{7}
Divide both sides by 7.
x=8
Divide 56 by 7 to get 8.
