15. Solving Equations
Let’s see what we recall from Algebra-1 to solve an equation for a missing variable??

16. Alg-1 Recall

18. What really Happened?
What steps really happen to solve that equation?

19. Equations??
What happens to a term anytime you move it to the other side of the = ?

22. Solving Equations
Get the variable terms together on the left side of the equation
Move all the numbers to the other side of the equation.
LAST step is always DIVISION (or Multiply by a reciprocal)

23. Example 1

24. Example 2

25. What about FRACTIONS??

26. GUIDED PRACTICE Solve the equation. 3 5 – 2. x + 1 = 4 SOLUTION 3 5 –
Write original equation. 3 5 –
x = 3
Subtract 1 from each side.
x = – (3) 5 3
Multiply each side by , the reciprocal of 5 3 –
x = – 5
Simplify.
ANSWER
The solution is 5.

27. In Class Practice
Work with your partner and solve the first 4 problems on the activity.
Check your answers on the website.

28. Word Problems
The bill for the repair of a car was $420. The cost of parts was $240. The cost of labor was $45 per hour. Write an equation and then solve for how many hours the repair took.

29. Solution:
Total cost: $420
Parts: $240
Labor: $45 per hour
Possible Equation:
Let “x” represent the # of hours
x = 420
x = 4 hours

30. In Class Practice
Work with your partner and solve the last word problem on the activity.
Check your answer on the website.

31. No Variables Left

32. No Variables No Solution All Real Numbers 2x + 4 = 2x – 3
When you subtract the 2x you end up with
4 = -3
This is not true
Meaning, there is no value for “x” to make this equation valid.
2x + 4 = 2x + 4
When you subtract the 2x you end up with
4 = 4
This is true
Meaning, that every value of “x” will make this equation valid
