360+648=21x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
1008=21x
Add 360 and 648 to get 1008.
21x=1008
Swap sides so that all variable terms are on the left hand side.
x=\frac{1008}{21}
Divide both sides by 21.
x=48
Divide 1008 by 21 to get 48.
