Answer:
The equation –7 + 9 = –9 + 7 is an example of an equation involving addition. To determine if the equation is true, false, or open, we can simplify each side of the equation separately and compare the results.
Starting with the left side of the equation:
–7 + 9 can be simplified as follows:
–7 + 9 = 2
Moving on to the right side of the equation:
–9 + 7 can be simplified as follows:
–9 + 7 = –2
Now, let's compare the results of each side:
2 (from the left side) is not equal to –2 (from the right side).
Therefore, the equation –7 + 9 = –9 + 7 is false because the left side and the right side of the equation do not have the same value.
To summarize, the equation –7 + 9 = –9 + 7 is false.
