Unit 4 · Lesson 11: Write Linear Equations

Objective: I will write and solve linear equations.

Vocabulary Steps:

Read for Understanding:

Read problems slowly. Stop for punctuation and identify

key words that indicate operations.

Define a Variable:

Identify the missing quantity in an equation. Before

writing and solving the equation, choose a variable and

state what the variable represents. Be sure to include

labels or units of measure.

Solve and Check:

Plug the solution back into the equation and check the

accuracy. Does the answer make sense with the question?

Is the answer reasonable?

*Reminder: Is, was, will be all indicate the = sign in a word

problem.

1. Read and pause at the punctuation
   to record thinking.


2. Circle keywords that indicate the
   operation to use.


3. Underline the question. This is the
   missing variable.


4. Write the equation and solve.


5. Plug the solution into the equation.


6. Check for reasonableness.

Example # 1 Example # 2

Directions: Write an equation and solve. Label your answer.

Two more than five times a number is 57.

x = a number

Solution:

5 푥푥+ 2 = 57

− 2 − 2

5 푥푥 = 55

푥푥= 11

Hank scored 32 points in a basketball game. This is 4

more than twice as many points as he scored the

week before. How many points did Hank score the

week before?

x = Hank’s points in previous game

Solution:

32 = 2푥푥+ 4

− 4 − 4

28 = 2푥푥

28

2 =

2 푥푥
