Question

(3a+5, 2b-5) = (2,1), then a+b =

Answer 1

Answer:

∴ a+b = 2

Step-by-step explanation:

given,

 (3a + 5, 2b-5) = (2,1)

here,

 3a+5 = 2

or, 3a = 2 - 5

or, a = -3 /3

∴ a = -1

again,

   2b-5 = 1

or, 2b = 1 +5

or, 2b = 6

or, b = 6/2

∴ b = 3

now,

∴ a + b = -1 + 3

          = 2
