A valid solution to the equation y = 6x - 18 is (x, y) = (4, 6).
How to find a solution to the linear equation
To find a solution to the linear equation y = 6x - 18, choose any value for x and then calculate the corresponding value of y using the equation.
Let's choose x = 4:
y = 6(4) - 18
y = 24 - 18
y = 6
Therefore, when x = 4, y = 6.
So, a valid solution to the equation y = 6x - 18 is (x, y) = (4, 6).
