The equation is $\"\"$ .

Solve by algebraically:

$\"\"$ (Original equation)

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

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

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

$\"\"$ (Cancel common terms)

Therefore, the solution is $\"\"$ .

$\"\"$

Solve by graphically:

The equation is $\"\"$ .

The related function is $\"\"$ .

Construct a table to graph the function.

Graph :

Draw a coordinate plane.

Graph the function $\"\"$ .

Plot the coordinate points $\"\"$ , $\"\"$ and $\"\"$ .

$\"\"$

Observe the graph :

The graph intersects the $\"\"$ -axis at $\"\"$ , hence the solution is $\"\"$ .
