Answer:
To find the solution of the proportion 3y-8/12=12y, we can start by simplifying the equation.
First, we can multiply both sides of the equation by 12 to eliminate the denominator:
12 * (3y-8)/12 = 12 * 12y
This simplifies to:
3y - 8 = 144y
Next, we can isolate the y term by subtracting 3y from both sides of the equation:
3y - 3y - 8 = 144y - 3y
This simplifies to:
-8 = 141y
Finally, we can solve for y by dividing both sides of the equation by 141:
-8/141 = y
Therefore, the solution of the proportion is y = -8/141.
