Question

5A + 15 is equal to b3 then
the value of a + b​

Answer 1

here A= 0

and B = 5 then

A+B = 5.....

Answer 2

Answer:

a + b = 9b + 25a + 30

Step-by-step explanation:

5a + 15 = 3b

Step 1: Get the value of a from the equation:

5a = 3b-15

a = (3b-15)/5

Step 2: Get the value of b

5a + 15 = 3b

3b -= 5a + 15

b = (5a + 15)/3

Step 3: Combine the two results to find the value of a + b

a + b  = (3b-15)/5  + (5a + 15)/3

         = {3(3b-15) + 5(5a +15)}/15

         = (9b -45 +25a +75)/15

         = (9b +25a + 75 - 45)/15

         = (9b +25a+30)/15

Therefore the value of a + b = (9b + 25a + 30)/15
