This is Lesson 1 introduction to equations unit 3 solving equations.
-9+7 = -2
are they the same?
On the left side:
-7 + 9 = 2
On the right side:
-9 + 7 = -2
Now that we have simplified each side of the equation, we can see that 2 does not equal -2. Therefore, the equation -7 + 9 = -9 + 7 is false.
