16. 1-Step Equations
7. EE.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

17. Vocabulary
Equation- a math sentence stating that 2 quantities are EQUAL Solution- the value of the variable that makes an equation true (the answer) Equivalent Equations- equations with the same solution

18. Isolate Inverse Operation TWO for Solving Equations + undoes –
Get the variable alone on one side of the equation
Inverse Operation
Operations that “undo” each other
+ undoes –
undoes +
x undoes ÷
÷ undoes x

19. x + 5 = 14. Isolate the Variable (circle the. operation
x + 5 = Isolate the Variable (circle the operation and number that are “in the way”)
Inverse Operation ( - undoes + )
x = 9 check:
9 + 5 = 14

20. Watch for the signs. Remember the sign comes IN FRONT of the term!!
x - 5 = 14 Isolate the Variable
Inverse Operation ( + undoes - )
x = 19 check:
= 14

21. Watch for the signs. Remember the sign comes IN FRONT of the term!!
You Try:
x + 8 = 11 Isolate the Variable
Inverse Operation
x = 11 check:
___ + 8 = 11

22. Watch for the signs. Remember the sign comes IN FRONT of the term!!
You Try:
23 = x - 11 Isolate the Variable
Inverse Operation
check:

23. Watch for the signs. Remember the sign comes IN FRONT of the term!!
You Try:
x + 11 = 23 Isolate the Variable
Inverse Operation ( + undoes - )
check:

24. Watch for the signs. Remember the sign comes IN FRONT of the term!!
𝑋 6 = Isolate the Variable
(6) 𝑥 = 10 (6) Inverse Operation (x undoes ÷) x = 60 check: = = 10

25. Watch for the signs. Remember the sign comes IN FRONT of the term!!
16 = 8x Isolate the Variable
16 8 = 8𝑥 Inverse Operation (÷ undoes x) = x check: 16 = 8(2)
16 = 16

26. Watch for the signs. Remember the sign comes IN FRONT of the term!!
You Try:
9x = Isolate the Variable
Inverse Operation
check:

27. Watch for the signs. Remember the sign comes IN FRONT of the term!!
You Try:
𝑋 2 = Isolate the Variable
Inverse Operation
check:

28. Watch for the signs. Remember the sign comes IN FRONT of the term!!
