Does x satisfy the equation?Finding all the values of the variable x that make the lefthandside of an equation equal the righthandside is called solving the equation for x. When we set out to find these values, x is called the unknown. Once we have found the values they are called the solutions or roots of the equation. We say that they make the equation true. We also say that these values of x satisfy the equation.
Is w=21 a solution of the equation ? A number is a solution to an equation if plugging it in results in a true statement.
Yes, 7=7. Is m=1 a solution of the equation m3=7? A number is a solution to an equation if plugging it in results in a true statement.
, so, m=1 is not a solution to the equation m3=7.
