\

The equations are $\"\"$ , $\"\"$ , $\"\"$ and $\"\"$ .

\

Solve each equation.

\

(i) $\"\"$ .

\

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

\

$\"\"$ (Apply additive inverse property : $\"\"$ )

\

(ii) $\"\"$ .

\

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

\

$\"\"$ (Apply additive inverse property : $\"\"$ )

\

(iii) $\"\"$ .

\

$\"\"$ (Add $\"\"$ on each side)

\

$\"\"$ (Apply additive inverse property : $\"\"$ )

\

(iv) $\"\"$ .

\

$\"\"$ (Add $\"\"$ on each side)

\

$\"\"$ (Apply additive inverse property : $\"\"$ )

\

The equation that does not belong is $\"\"$ .
