The equation is $\"\"$ .

Apply subtraction property of equality: If a = b then a $\"\"$ c = b $\"\"$ c.

$\"\"$ (Subtract 16 from each side)

$\"\"$ (Apply additive inverse property: 16 $\"\"$ 16 = 0)

$\"\"$ (Subtract: 31 $\"\"$ 16 = 15) $\"\"$

Apply division property of equality: If a = b then $\"\"$ .

$\"\"$ (Divide each side by 5)

$\"\"$ (Cancel common terms)

$\"\"$ (Divide: $\"\"$ ) $\"\"$

Check:

To check the solution, substitute $\"\"$ in original equation.

$\"\"$

$\"\"$ (Multiply: $\"\"$ )

31 = 31 (Add: 16 + 15 = 31)

The statement is true. $\"\"$

The value of $\"\"$ .
