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
