b.
Answer to Problem 1P
The equivalent equation is
Explanation of Solution
Given information:
The equation:
Calculation:
The given equation is
Subtract 13 from each side of the above equation.
Thus, the equivalent equation is
If 13 is subtracted from each side of the given equation, then it is seen that it will not give any solution of the equation. It will make another equation which is equivalent to the given equation.
Hence, the equivalent equation is
