Evaluate z-(y÷3-1) when y = 3 and z = 7.

Step-by-step explanation:
Greetings!
Given expression to be evaluated
[tex]z - (y \div 3 - 1)[/tex]
where,
Thus, plug in these values to the system and evaluate it so,
[tex]7 - (3 \div 3 - 1)[/tex]
Follow the PEMDAS order of operation
calculate the parentheses (3÷3-1)
where division precedes subtraction/addition so we get the value
[tex]7 - (1 - 1) \\ 7 - 0 = 7[/tex]
=7
following the above method and instructions solve for the image problem
Finally, you will get the value. of 2.
Though If you have any questions comment me.
Hope it helps!
