Writing Equations

Simple Equations

2 (x) = 10

2 + x = 10

We need to identify the Variable the
operation and the total in both equations.

Solve: Jacqueline has $5 more than Samanta. If
Jacqueline has $15 dollars how much does
Samantha have? Write and solve the equation

What is the variable? S = amount of money samanta has.

What is the operator? addition

Equations: S + 5 = $15

Answer: S = $10; Samantha has $10

Step 1: Read the question!!!

Step 2: What is the operation? (are we growing?
Getting Smaller? Putting into groups? What is
happening?)

Step 4: What is the variable?
(what are we looking for)

Step 5: What is the total?

The equation is:
