Step-by-step explanation:

Greetings!

Given expression to be evaluated

[tex]z - (y \div 3 - 1)[/tex]

where,

  • y=3 & z=7

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!
