Final answer:

To find x when y = 3, substitute the given x and y values into the equation y = 7 and solve for x.

Step-by-step explanation:

To find the value of x when y = 3, we can use the given equation y = 7 when x = 2. Since we know that y = 7 when x = 2, we can substitute the values into the equation to solve for x.

7 = 3x + 9

Subtracting 9 from both sides, we get:

-2 = 3x

Dividing both sides by 3, we find:

x = -2/3
