Answer 1

The x-value of the solution for the given system of equations can be found by solving the equations. Let's solve the system of equations:

From the first equation:
-x + 2y = 6

Rearranging this equation, we have:
x = 2y - 6

Substituting this value of x into the second equation, we get:
6y = (2y - 6) + 18

Simplifying this equation, we have:
6y = 2y + 12

Subtracting 2y from both sides, we get:
4y = 12

Dividing both sides by 4, we get:
y = 3

Now, substituting this value of y back into the first equation, we get:
-x + 2(3) = 6

Simplifying this equation, we have:
-x + 6 = 6

Subtracting 6 from both sides, we get:
-x = 0

Dividing both sides by -1, we get:
x = 0

Therefore, the x-value of the solution is 0.

The correct answer is:
0
