Explanation of Solution
Given information:
Calculation:
Divide both sides of the given equation
(b)
To find: The solution of the equation.
(b)
Answer to Problem 12OE
The solution of the equation is infinite.
Explanation of Solution
Given information:
Calculation:
Since
Therefore, the solution of the equation is
(c)
To find: Whether you get an equivalent equation if an equation multiplies by zero.
(c)
Answer to Problem 12OE
Yes, it gives an equivalent equation.
Explanation of Solution
Given information: An equation is multiply by zero.
Calculation: If we multiply zero on both sides of the equation, it give zero every time. Therefore, the result will be the same for an equation. This means it will be equivalent equation.
(d)
To explain: The reason why each side of an equation is not possible to divide by zero.
(d)
Answer to Problem 12OE
Yes, it gives an equivalent equation.
Explanation of Solution
Given information: Each side of an equation is divided by zero.
The zero in the dominator gives the undefined result. Therefore, it is not possible to divide an equation by zero.
