an equation is a mathematical expression that has two perfectly balanced sides, they have the sign = between them.
\n" ); document.write( "You must keep them balanced, so whatever you do to one side you also do to the other.
\n" ); document.write( "Example:
\n" ); document.write( "x-3 = 5, find the value of x.
\n" ); document.write( "Let's add 3 to both sides
\n" ); document.write( "x-3+3 = 5+3 on the left -3 and +3 cancel each other and you get:
\n" ); document.write( "x = 5+3 = 8
\n" ); document.write( "x = 8
\n" ); document.write( "Is this correct? Let's check the original equation:
\n" ); document.write( "x-3 = 5 substitute the x with 8
\n" ); document.write( "8-3 = 5 Correct
\n" ); document.write( "
