Topic #22:
Benchmark:MA.7.2.3: Apply inverse relationships between addition and subtraction, and multiplication and division, to solve one- step problems.

3. Definition:
Operations that “undo” each other. Multiplying and dividing are inverse operations and so are addition and subtraction.

4. Example/ Drawing/ Formula:
First you do the inverse of multiplying 3 which is dividing 3. That cancels out. Then I do 6/3, which equals 2. Next, you take the 9x and divide by 9 which now means you are left with x. Now you bring the 2 down and divide 2 and 9 (2/9). Therefore, x= 2/9.
Equation: 9x * 3 = 6
9x * 3 = 6
/3 /3
9x = 2
/ /9
x = 2/9

5. Create A Question:
Can you solve this equation?

6. My Question:
14x / 4 = 7

7. Solution to question:
x= 2
How did I get 2? Here… look at this

8. Explanation To Question:
What you have to do is do the inverse of dividing 4 which is multiplying 4. That cancels out. Then you do the same to the other side. 7x4=28. Bring that down(28). Next, 14x/14equals it canceling out. X is left over. So, 28/14=2. Therefore, x=2.
14x / 4 = 7
