Question

What is 9x + 100 = 829

Answer 1

Answer: x = 81

Explanation:

You'd want to isolate x, meaning subtracting 100 on both sides to remove that from the equation. This results in 9x = 729, divide by 9 on both sides to remove that too from the equation and you'd be left with x = 81.

Answer 2

81

Explanation:

9x + 100 = 829

9x =829-100

= 729

x = 729/9

x = 81
