Lesson 4-2: Solving Systems – Substitution & Linear Combinations Objectives: Students will: Solve systems of equations using substitution and linear combinations. 5.3 Solving Systems of Linear Equations by Elimination
The three methods for solving systems of equations are substitution, elimination, and graphing. In the substitution method, we solve one of the equations for one of its variables. Then, replace that variable in the other equation with the expression derived in the first step. From there, we...

PSAT System of Equations: Substitution To solve a system of two linear equations by substitution, do the following: • Isolate a variable (ideally, one whose coefficient is 1) in one of the equations. • Substitute the result into the other equation. Let’s examine a sample problem to...
Each equation represents a plane in 3 dimensions, and the point of intersection, P(4, −3, 3), is the point common to all 3 planes. (Try substituting that point in the equations for the 3 planes. It works each time. We will learn how to find this point of intersection later in ...

Generally, it is not possible to deduce an element's equation of state or phase diagram from first principles; they must be experimentally determined.As expected, chemical compounds are far more involved than the chemical elements. [At least they are usually are: the main group hydrides and ...
