To solve the proportion 4y-10/12 = y/10, we need to cross multiply and solve for y.
First, cross multiplying we get:
(4y-10)(10) = 12(y)
Expanding the left side, we get:
40y - 100 = 12y
Next, we can combine like terms by subtracting 12y from both sides:
40y - 12y - 100 = 0
Simplifying the left side, we get:
28y - 100 = 0
To isolate y, we can add 100 to both sides:
28y - 100 + 100 = 0 + 100
Simplifying, we get:
28y = 100
Finally, to solve for y, we can divide both sides by 28:
28y/28 = 100/28
Simplifying, we get:
y = 100/28
The solution to the proportion is:
y = 25/7 or approximately 3.57
