ok lets say you have 20x = 30
the answer to the equation would be x = 30/20 or 3/2

anonymous · Answer

your goal was to find the value of x by doing this you have solve the unknown in the equation

anonymous · Answer

A solution to an equation means that it satisfies the equal sign and evaluates as true. For example: 2x-5=12 --> x=(12+5)/2 --> x=8.5 

You can check this: 2*8.5-5=12 <-- this equality is satisfied and evaluates as true.

12=12 Twelve is equal to twelve; how very true!
