Question

3a = 27b + 1 and 5b = 25a -1, then a + b =​

Answer 1

Answer:

a+b = 0

Step-by-step explanation:

3a = 27b+1

a = (27b+1)/3

a = 9b + 1/3

5b = 25a - 1

b = (25a-1)/5

b = 5a - 1/5

b = 5(9b + 1/3) - 1/5

b = 45b + 5/3 - 1/5

b = 45b + 25/15 - 3/15

b = 45b +22/15

22/15 = -44b

-22/15 * 1/44 = b

-1/30 = b

a = 9(-1/30) + 1/3

a = 3(-1/10) + 1/3

a = -3/10 + 1/3

a = -9/30+ 10/30

a = 1/30

a+b = 1/30 + ( -1/30)

a+b = 0
