Let's solve the equation step by step:
168 - (98 - z) = 65
First, we need to solve the expression inside the parentheses:
98 - z
We can rewrite this as:
-1 * (z - 98)
Now, let's substitute this back into the original equation:
168 - (-1 * (z - 98)) = 65
Next, we can simplify the equation by removing the double negatives:
168 + (z - 98) = 65
Let's simplify the left side of the equation:
168 + z - 98 = 65
Now, let's combine like terms:
z + 70 = 65
Next, let's isolate the variable z by subtracting 70 from both sides of the equation:
z = 65 - 70
Simplify the right side of the equation:
z = -5
So, the solution to the equation is z = -5.
