Final answer:
The values of x and y in the expressions (2x+7)⋅(12y+1)⋅(3x−7) are x = -7/2 and y = -1/12.
Step-by-step explanation:
To solve for the values of x and y in the given expression, set each factor equal to zero and solve for the variables. First, set (2x+7) equal to zero:

Subtract 7 from both sides:

Divide by 2:

Next, set (12y+1) equal to zero:

Subtract 1 from both sides:

Divide by 12:

Finally, set (3x−7) equal to zero:
\(3x - 7 = 0\)
Add 7 to both sides:

Divide by 3:

However, this solution contradicts the first value of x (-7/2) obtained earlier. Therefore, the correct solution for x is x = -7/2. The final values for x and y are x = -7/2 and y = -1/12.
