Question

1. 9x + 18y = 0

Explanation:

Step1: Identify the GCD of coefficients

The coefficients of \(x\) and \(y\) are 9 and 18. The greatest common divisor (GCD) of 9 and 18 is 9.

Step2: Divide each term by GCD

Divide each term in \(9x + 18y = 0\) by 9.
\(\frac{9x}{9}+\frac{18y}{9}=\frac{0}{9}\)
Simplify each term: \(x + 2y = 0\)

Answer:

The simplified form of \(9x + 18y = 0\) is \(x + 2y = 0\)
