Rules for Solving 1-Step Equations:
Step 1:
Identify the variable.
Variable- the letter in the problem, it’s what you are
solving for
à
it can be any
letter, NOT JUST X OR Y
For
example:
1. 7y = 49
à “Y” IS THE VARIABLE
2. f - 14 = 24
à
“f” IS THE VARIABLE
You try: Identify the variable
1. 3x = 36
à
___________________
2. n + 11 = 27
à
___________________
3. 25t = 100
à ___________________
Step 2:
Find out what operation that the problem is.
(x, ÷, +, or -)
For example:
8n = 16 à
This is multiplication (x)
z + 10 = 15
à
This is addition (+)
Step 3: Do
the OPPOSITE operation to BOTH sides of the = sign to
solve the problem. This gets the variable by itself!
Remember
that you have to get the variable by itself to find the answer!! *
Directions: Solve each 1-Step Equation by finding the variable.
1.
4j = 12
Step 1: Identify the
variable. à ___________________
Step 2: What operation is
it. à
___________________
Step 3: Do the OPPOSITE
operation. à ___________________
(to both
sides)
Step 4: Write the
answer à
___________________
(j = __ )
_______________________________________________________
2.
56 – k =
43
Step 1: Identify the
variable. à ___________________
Step 2: What operation is
it. à
___________________
Step 3: Do the OPPOSITE
operation. à ___________________
(to both
sides)
Step 4: Write the
answer à
___________________
(k = __ )
