is -7+9=-9+7 true, false, or open.
To determine if the expression "-7+9=-9+7" is true, false, or open, let's solve both sides of the expression separately:
On the left side:
-7 + 9 = 2
On the right side:
-9 + 7 = -2
Since 2 is not equal to -2, the expression "-7+9=-9+7" is false.
To determine if the equation -7 + 9 = -9 + 7 is true, false, or open, we can simplify both sides of the equation and compare the results.
On the left side of the equation, -7 + 9 equals 2.
On the right side of the equation, -9 + 7 also equals 2.
Since 2 is equal to 2, we can conclude that both sides of the equation are equal, and therefore the equation -7 + 9 = -9 + 7 is true.
In summary, the equation -7 + 9 = -9 + 7 is true.
-7+9=-9+7
