Question

1. \\(\frac{n - 7}{9} = -3\\)

Explanation:

Step1: Multiply both sides by 9

To eliminate the denominator, we multiply each side of the equation $\frac{n - 7}{9} = -3$ by 9. This gives us $9\times\frac{n - 7}{9}=9\times(-3)$.
Simplifying both sides, the 9 in the numerator and denominator on the left cancels out, so we have $n - 7=-27$.

Step2: Add 7 to both sides

To solve for $n$, we add 7 to both sides of the equation $n - 7=-27$. So, $n - 7 + 7=-27 + 7$.
Simplifying both sides, we get $n=-20$.

Answer:

$n = -20$
