__**Balance Method**__
by: Maya

5X-6=2x-21 To solve the equation you must balance it so if you subtract the 6 from one side you subtract it from the other too. 5x-6+6=2x-21-6 5x=2x-15 Then you must continue to balance by putting all the x’s on one side. 5x-2x=2x-2x-15 3x=15 Then you must get x by itself by division. 3x=15 3 3 x=5

This are things that you cannot do- Cannot have exponents (or powers) > For example, //x// squared or //x// 2

Cannot multiply or divide each other > For example: "x" times "y" or xy; "x" divided by "y" or x/y

Cannot be found under a root sign or square root sign (sqrt) > For example: Ö x or the "square root of x"; sqrt (x)
