Let's solve the following equation:

(5x + 1) + (16x - 1) =9

Step 1: Solving the parentheses:

5x + 1 + 16 x - 1 = 9

Step 2: Like terms:

5x + 16x = 9 + 1 - 1

21x = 9

Step 3: Dividing by 21

21x/21 = 9/21

x = 9/21

Step 4: Simplifying:

x = 9/21

Dividing by 3 numerator and denominator:

x = 3/7

Step 5: Let's prove that x = 3/7 is correct

5 (3/7) + 1 + 16 (3/7) - 1 = 9

15/7 + 48/7 = 9

63/7 = 9

Yaha, what do you think? Is x = 3/7 correct?
