Lesson 5.4 Variables and Equations
*I can
write and solve equations
*Vocabulary: equation, variable
*Use
opposite operations to solve equations with variables
*Always
check your answers and show your work
Example:

Lesson 5.5 Problem Solving: Write an
Equation
*I can
write equations to represent and solve problems.
*Remember:
1. First,
you need to look to see which information we have already and which information
we need to find out.
2. We use
a variable to represent the information we need to find out.
3. Write
an equation to help you solve the problem.
4. Solve
the equation. Find out what the variable equals. (ex. n = 7)
5. Check
if the equation is true. Substitute your answer for the variable in the
equation and solve.
6. Write
the answer to the question in a full sentence.
