Multiply both sides of the equation by -20.
Simplify the equation to isolate A.
Obtain the solution A = 0.
The final answer is 0 .
Explanation
Understanding the Problem We are given the equation − 20 A = 0 and our goal is to solve for the variable A . This means we want to isolate A on one side of the equation.
Isolating the Variable To isolate A , we need to get rid of the − 20 in the denominator. We can do this by multiplying both sides of the equation by − 20 . This gives us: − 20 A × ( − 20 ) = 0 × ( − 20 ) On the left side, the − 20 in the numerator and denominator cancel out, leaving us with just A . On the right side, 0 multiplied by any number is 0 . So we have: A = 0
Final Answer Therefore, the solution to the equation − 20 A = 0 is A = 0 .
Examples
Imagine you're dividing a certain amount of money (A) among 20 people, and each person receives a negative amount (-20, meaning they owe money). If the total amount distributed is zero, then the original amount (A) must have been zero. This type of problem helps in understanding basic algebraic manipulations and their applications in real-world scenarios involving division and distribution.
