In this lecture, you will cover Multiplication and Division Techniques to help you isolate the variable in more complicated equations. By using the two new principles along with the strategy of opposite operations, you will have no problem figuring out the four examples.
For more complex
equations, isolate the variable and solve the equation by using the
multiplication property of equality. If you multiply each side of
an equation by the same quantity, the resulting equation has the
same solutions as the original one.
You can also
isolate the variable and solve the equation by using the division
property of equality. If you divide each side of an equation by the
same nonzero quantity, the resulting equation has the same
solutions as the original one.
properties to convert an equation in which the variable has a
coefficient different from 1 into an equation in which the
coefficient is 1.
