Answer 1

Х+6=а
х=а-6
12=а-6
а=18

Answer 2

Solving for the Value of "a" in the Equation x + 6 = a

To find the value of "a" in the equation x + 6 = a such that the root of the equation x + 6 = a is 12, we can follow these steps:

1. Identify the Given Equation: The given equation is x + 6 = a.

2. Find the Value of "a" for the Given Root: We need to find the value of "a" such that the root of the equation x + 6 = a is 12.

3. Solve for "a": To solve for "a", we can use the given root and the equation x + 6 = a.

Solution Steps

We can solve for the value of "a" using the given root and the equation x + 6 = a.

The given equation is x + 6 = a.

Given root: x = 12

Substitute the value of x into the equation: 12 + 6 = a

Simplify the equation: 12 + 6 = a 18 = a

Conclusion

To make the root of the equation x + 6 = a equal to 12, the value of "a" needs to be 18.
