The equation is $\"\"$ .

According to multiplication property of equality:

For any number a, b and c, If a = b then ac = bc.

$\"\"$ (Multiply each side by $\"\"$ 2)

$\"\"$ (Cancel common terms)

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

$\"\"$

According to subtraction property of equality: If a = b then a – c = b – c.

$\"\"$ (Subtract 4 from each sides)

$\"\"$ (Cancel common terms)

b = 30 (Subtract: $\"\"$ )

$\"\"$

Check:

To check the solution, substitute b = 30 in original equation.

$\"\"$

$\"\"$ (Add: 30 + 4 = 34)

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

Compare the values, the equation is true. The solution is b = 30.

$\"\"$

The value of b = 30. \ \
