z-6
z+9 =4/7 =109/7
I hope this is correct, please help

Ann/Sam, none of your problems make sense.
I have no idea what you are trying to do.
To determine if the given equation is correct, we need to solve it for the variable z and check if the solution satisfies the equation. Let's go through the steps:
1. Start with the equation: z + 9 = 4/7
2. To isolate the variable z, subtract 9 from both sides of the equation:
z + 9 - 9 = 4/7 - 9
z = 4/7 - 63/7
3. Find a common denominator for 4/7 and 63/7, which is 7, so we have:
z = (4 - 63)/7
4. Evaluate the numerator:
z = -59/7
Therefore, the solution to the equation z + 9 = 4/7 is z = -59/7.
Now, to check if this solution is correct, we can substitute z = -59/7 back into the original equation and see if it holds true.
Substituting z = -59/7 into z + 9 = 4/7:
(-59/7) + 9 = 4/7
Now, let's calculate both sides of the equation:
-59/7 + 9 = -59/7 + 63/7
= (4/7)
As we can see, when we substitute z = -59/7, both sides of the equation are equal to 4/7. Therefore, our solution is correct.
So, the equation is correct and the solution is z = -59/7.
