Balancing Equations
Think of equations as a scale where both sides must remain perfectly balanced no matter what. If
you remove something from one side of the scale, then something of equal value must
Equations with Zero or Infinite Solutions
So far, were addressed how to balance an equation in order to obtain a solution and resulting
form obtained when its balanced. But sometimes, we wont always g
Linear Equations and Word Problems
Often times in algebra (and beyond), you will be given a word problem where you are given no
equations whatsoever and expected to come up with the equations yourself
PEMDAS
Often times in Algebra I and beyond, you will encounter an equation that looks like this:
3*5+63/3
And you will be told to evaluate what number this is. Naturally, you will evaluate it going fr
Inequalities
An inequality is an equation where instead of an equal sign, we have either a:
-Less than sign (<)
-Greater than sign (>)
-Less than or equal to sign (<)
-Greater than or equal to sign (>
System of Equations
A system of equations is a set of two or more equations which share the same set of
variables/unknowns. When we are solving a system of equations, we are trying to find the
