To solve an equation you isolate the variable you are asked to solve for.The addition principle says that when a=b,a+c=b+c for any nymber c.
We use the addition principle to find the unknown variable.
Along the same lines,the multiplication principle says that if a=b and c is any number,a*c=b*c.
This principle is also used to help isolate the variable you are asked to solve for.
