Evaluate Using the Given Value z-(y÷3-1) ; use y=3 ; and z=7

$z - (y \div 3 - 1)$ ; use $y = 3$ ; and $z = 7$

Step 1

Replace the variable $y$ with $3$ in the expression.

$z - (3 \div 3 - 1)$

Step 2

Replace the variable $z$ with $7$ in the expression.

$(7) - (3 \div 3 - 1)$

Step 3

Simplify each term.

Divide $3$ by $3$ .

$7 - (1 - 1)$

Subtract $1$ from $1$ .

$7 - 0$

Multiply $- 1$ by $0$ .

$7 + 0$

Step 4

Add $7$ and $0$ .

$7$
