Answer 2

To solve the equation, we need to find the value of 'z'. The equation is:

13z - 10.5z = 16.4275

Step 1: Combine like terms on the left side of the equation: (13 - 10.5)z = 16.4275 2.5z = 16.4275

Step 2: Now, isolate 'z' by dividing both sides of the equation by 2.5: z = 16.4275 / 2.5 z = 6.57

Now, let's verify the solution by substituting 'z' back into the original equation:

13z - 10.5z = 16.4275

Substitute z = 6.57:

13 * 6.57 - 10.5 * 6.57 = 16.4275

85.41 - 68.985 = 16.4275

16.425 = 16.4275 (Approximately, as there might be some rounding errors due to the decimal places)

The left-hand side of the equation is approximately equal to the right-hand side, confirming that the value of 'z' is correct.
