Options

• −4

• 6

• 4

• −6

Answer 1

For equation `x/3 - y/2` = 1, the value of y for x = 9 is 4.

Explanation:

Substituting x = 9 into the equation \[\frac{x}{3} - \frac{y}{2} = 1\]:

\[\frac{9}{3} - \frac{y}{2} = 1 \implies 3 - \frac{y}{2} = 1 \implies -\frac{y}{2} = 1 - 3 \implies -\frac{y}{2} = -2 \implies y = 4\]
