Answer 2

Solving the Equation for the Value of "a"

To find the value of "a" that makes the equation \(42 - (a \times x) = 16\) equal to 18, we can follow these steps:

1. Start with the given equation: \(42 - (a \times x) = 16\). 2. Substitute the value of 18 for the entire equation: \(42 - (a \times x) = 18\). 3. Solve for the value of "a" that satisfies the equation.

Calculation

To solve for the value of "a", we can rearrange the equation to isolate "a":

\[42 - (a \times x) = 18\]

Subtract 42 from both sides:

\[-(a \times x) = 18 - 42\]

\[-(a \times x) = -24\]

Divide both sides by -x:

\[a = \frac{-24}{-x}\]

So, the value of "a" that makes the equation \(42 - (a \times x) = 16\) equal to 18 is \(\frac{24}{x}\).

Conclusion

The value of "a" that needs to be substituted in place of "a" to make the equation \(42 - (a \times x) = 16\) equal to 18 is \(\frac{24}{x}\).
