5.03 Solving one-step equations

2. Order of Operations
PEMDAS right to left to solve: 9−3×2+5 (multiplication) 9−6+5 (subtraction) 3+5 (addition) 8

3. Solving One Step Equations
Opposite of PEMDAS; SADMEP.
S – subtraction
A – addition
D – division
M – multiplication
E – exponents (remember, we haven’t
P – parenthesis talked about these yet!)

4. One Step Equations
-Perform 1 step to solve -Try to get “X” by itself -Do the same operation to both sides -Just like what you did on excel math:

5. Excel Math
+ 3 = 5
Now, we use X as a place holder instead of the empty square.
X + 3 = 5

6. What you do to ONE side, you MUST do to the other.
X + 3 = 5
(Subtract 3 from both sides)
X = 2

7. 2X = X = 5 6 – 1X = X = X = 4

8. Foamy Squishy Things Introduction
= X + = 0 = 1 = -1

9. X + 3 = 5
You can also use foamy squishy things to solve problems. + = =

10. Using Foamy Squishy Things
Set up your foamy squishy things in the form of this problem:
X + ˉ5 = 2
