Algebra.Com's Answer #730084 by addingup(3677)![]() ![]() You can put this solution on YOUR website! 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( " |
