To solve the equations:
O + O + O = 30
1 - 3 - 5 - 7
9 - 11 -
15
We can start by simplifying the second equation:
1 - 3 - 5 - 7 = -14
9 - 11 - x = -14
To find the value of x, we can solve the equation:
-11 - x = -14
Adding 11 to both sides of the equation:
-11 + 11 - x = -14 + 11
Simplifying:
-x = -3
Multiplying both sides by -1:
(-1) * (-x) = (-1) * (-3)
x = 3
Now, substituting the value of x back into the second equation:
9 - 11 - 3 = -14
-5 - 3 = -14
-8 = -14
This is not a true statement. Therefore, the values provided do not satisfy the equations given.
