Gnom [1K]

Answer:

n=-30

Explanation:

Given the equation:

$\frac{n}{-3}-2=8$

Step 1: Add 2 to both sides.

$\begin{gathered} \frac{n}{-3}-2+2=8+2 \\ \frac{n}{-3}=10 \end{gathered}$

Step 2: Multiply both sides by -3.

$\begin{gathered} \frac{n}{-3}\times-3=10\times-3 \\ n=-30 \end{gathered}$

The solution to the equation is n=-30,

$6r+5=11r\ \ \ \ |\text{subtract 6r from both sides}\\\\5=5r\ \ \ \ |\text{divide both sides by 5}\\\\\boxed{r=1}\\-------------------------\\\dfrac{2x-4}{2}=6x+3\\\\\dfrac{2x}{2}-\dfrac{4}{2}=6x+3\\\\x-2=6x+3\ \ \ \ \ |\text{add 2 to both sides}\\\\x=6x+5\ \ \ \ |\text{subtract 6x from both sides}\\\\-5x=5\ \ \ \ \ |\text{divide both sides by -5}\\\\\boxed{x=-1}$
