Answer :
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?
