$\"\"$

Write an equation involving addition and demonstrate two ways to solve it.

For example:

Consider an equation $\"\"$ .

The equation can be solved by either subtracting $\"\"$ (or) adding $\"\"$ to both sides of the equation.

Case(i):

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

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

Case(ii):

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

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

$\"\"$

The equation $\"\"$ can be solved by either subtracting $\"\"$ (or) adding $\"\"$ to both sides of the equation.
