Basic Lesson. Demonstrates the skill of balancing the left and right side of an equation. Also, introduces expressions. A value, such that, when you replace the variable with it, it makes the equation true. Left side = Right side Simplifying each side using the distributive rules, eliminating parentheses, and combining like terms.
These equations can become more complicated, but each and every time we will use the logarithm law to transform an exponential equation into one that is more familiar (linear, quadratic, etc). Exercise #3: Solve each of the following equations for x. Round your answers to the nearest hundredth x+3 = 50 log 6 = log50 (x + 3)log6 = log50 x 3 = log 50

A system of linear equation comprises two or more linear equations. The solution of a linear system is the ordered pair that is a solution to all equations in the system. One way of solving a linear system is by graphing. The solution to the system will then be in the point in which the two equations intersect.
Learn algebra using 19 graph-related activities on four key topics: linear equations, quadratic equations, transformations of functions and exponential functions. Apply algebraic concepts using both real-world problems and "pure" math.
The following lesson is on multi-step linear equations. Just in case you did not know, you want to have mastered one and two step equations before watching this lesson. Multi-step equations are the foundation of algebra and more advance math- there importance can not be overstated.
7.3 GRAPHING FIRST-DEGREE EQUATIONS. In Section 7.1, we saw that a solution of an equation in two variables is an ordered pair. In Section 7.2, we saw that the components of an ordered pair are the coordinates of a point in a plane. Thus, to graph an equation in two variables, we graph the set of ordered pairs that are solutions to the equation.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
