Warmup! "By the end of today's class I will be able to..."
Today's Agenda &
Reminders
• EQAO Practice Assignments DUE!! Hand in!!• Polynomials Test Grade < 50%? Rewrite test before Friday to receive a passing grade. Arrange with me after class. • Lesson: Solving Simple Equations
"The answer to the problem you are solving is of far less importance than what you learn by solving it."
• Solve simple equations by isolating a variable using opposite operations.

Unit 2: EquationsLesson 1: Solving Simple Equations
What is the difference between a mathematical expression and equation?
An expression is simply a mathematical phrase made up of numbers and variables, connected by operators.Ex) x + 3 or 7 are expressions (binomial & monomial respectively)
An equation is a mathematical statement that says two expressions are equal. Ex) x + 3 = 7
Note that equations have only one value for the variable which makes the two expressions equal. In order to solve equations involving more than one variable, we must simultaneously solve more than one equation. For now, we will focus on only solving equations with one variable.

When solving equations, we will use the method of "opposite operations" to isolate our variable.

When solving equations with multiple operations, we use reverse BEDMAS (SAMDEB) to decide which step to do first in isolating our variable.

"The answer to the problem you are solving is of far less importance than what you learn by solving it."
• Correctly identify the opposite operation to use when isolating a variable in an equation.• Find the root of simple one or two step equations. Ex) Solve 3x + 2 = 11
