a) 5x - 11 = 3x + 9

(b) 3y + 4 = 7 - 2y

(c) 9 - 2(x - 5) = x + 10 

(d) 5(y - 1) = 3(2y - 5) - (1 - 3y) 

(e) 2(x - 1) - 6x = 10 - 2(x - 4) 

(f) x/3 - (x - 2)/2 = 7/3

(g) (x - 3)/4 + (x - 1)/5 - (x - 2)/3 = 1 

(h) (3y - 2)/3 + (2y + 3)/3 = (y + 7)/6

(i) (8x - 5)/(7x + 1) = -4/5

(j) (5 - 7x)/(2 + 4x) = -8/7

(k) (x - 2)/(x - 3) = (x - 1)/(x + 1) 

(l) (2x - 5)/(3x - 1) = (2x - 1)/(3x + 2) 

(m) (3 - 7x)/(15 + 2x) = 0 

(n) (0.4y - 3)/(1.5y + 9) = -7/5

(o) 2/(3x - 1) + 3/(3x + 1) = 5/3x 

(p) 2/(x - 3) + 1/(x - 1) = 5/(x - 1) - 2/(x - 2) 

(q) 15(x - y) - 3(x - 9) + 5(x + 6) = 0 

(r) y/2 - 1/2 = y/3 + 1/4

(s) (0.5y - 9)/0.25 = 4y - 3 

(t) [17(2 - y) - 5(y + 12)]/(1 - 7y) = 8
