1. (x-1)/2=(x+1)/3+1
(x-1)/2 = (x+1+3)/3
3x - 3 = 2x + 8
x = 5
2. (t+13)/5=1/5-(t+5)/2
2t + 26 = 2 - 5t - 25
7t = -49
t = -7
3. (u-1)/2-(u+1)/8=u/4
4u - 4 - u - 1 = 2u
u = 5
4.y/4-(2(y-9))/3=(5y+8)/6
3y - 8(y-9) = 10y + 16
3y - 8y + 72 = 10y + 16
15y = -56
y = -56/15
5.1/6(1/2(1-2n)+1/3)=n/3
(1/2)(1-2n) + 1/3 = 2n
3(1-2n) + 2 = 12n
3 - 6n + 2 = 12n
