(7/2)y - (1/2)y = (-1/2) - (17/2)
(6/2)y = -18/2
3y = -9
y = -3

Write the equation out 7/2y + 17/2 = 1/2y - 1/2
Put the like variables on the same side 7/2y - 1/2y = -17/2-1/2
Add the variables 6/2y = 18/2 reduce 3/y = -9
multiply by (-1) -3/y = 9 multiply by (y ) -3 = 9y
solve -3/9 = y therefore y = -1/3

7/2y + 17/2 = 1/2y - 1/2
transpose 1/2y
7/2y + 17/2 - 1/2y = 1/2y - 1/2 - 1/2y
Collect like terms
6/2y + 17/2 = - 1/2
Transpose 17/2
6/2y + 17/2 - 17/2 = - 1/2 - 17/2
Collect like terms
6/2y = - 18/2
Multiply both sides of the equation by 2
2(6/2y) = 2(- 18/2)
6y = - 18
Divide both sides of the equation by 6
6y / 6 = - 18 / 6
y = - 18/6
y = - 3

If you are looking for y, my answer is -3... My equation is as follows:
7/2y + 17/2 = 1/2y - 1/2
Group Similar terms:
7/2y - 1/2y = -1/2 - 17/2
Simplify:
6/2y = -18/2
3y = -9
Divide both sides by 3:
y = -3

what??
7/2y + 17/2 = 1/2y - 1/2
17/2 + 1/2 = 1/2y - 7/2y
18/2 = -6/2y
9 = -3y
-3 = y

Only in America could people mess up this problem.
7/2y-1/2y=-17/2-1/2
6/2y=-18/2
3y=-9
y=-3

7/2y + 17/2 = 1/2y - 1/2
17/2 + 1/2 = 1/2y - 7/2y
18/2 = -6/2y
9 = -6/2y
9(2y) = -6
18y = -6
y = -6/18
y = -1/3

7/2y + 17/2 = 1/2y - 1/2
7/2y + 17y/2y = 1/2y - y/2y
(7 + 17y) / 2y = (1 - y) / 2y
7 + 17y = 1 - y
18y = -6
y = -1/3
My answer is definitely correct. I had already double check
