To solve the equations given, we need to isolate the variable 'y' in each equation.

(y - 6.5)/7 = 0.5
First, multiply both sides of the equation by 7 to get rid of the denominator:
y - 6.5 = 3.5
Now, add 6.5 to both sides:
y = 10

8.4/(y - 2) = 4
First, multiply both sides of the equation by (y - 2) to get rid of the denominator:
8.4 = 4(y - 2)
Expand the right side:
8.4 = 4y - 8
Add 8 to both sides:
16.4 = 4y
Finally, divide by 4 to solve for y:
y = 4.1

Therefore, the solutions to the equations are:
y = 10
y = 4.1
