1/9 = 0.111...
9/9 = 0.999... but also 1 because 9 divided by 9 is 1. Add 8 to both sided to get 8.9999... and 9

You can't, it has been done before but there is a fault in the working because the 2 numbers are different. If you want to see a video of someone attempt it, I believe there is a video on the numberphile channel.

Hope this helps :)

Beef hope me I need you to answer the question. What is n * 54 - 688-20 =???³

Answer:n= 1/3d - 2/3m

Step-by-step explanation:

d=2m+3n

Step 1: Flip the equation.

2m+3n=d

Step 2: Add -2m to both sides.

2m+3n+−2m=d+−2m

3n=d−2m

Step 3: Divide both sides by 3.

3n/3 = d-2m/3

Therefore

n= 1/3d - 2/3m

Hope this helps!

Answer:

n = d - 2m

Step-by-step explanation:

First we want to get n alone on one side, so we should subtract 2m from both side;

d = 2m + 3n

3n = d - 2m

Now to get n by itself, we need to divide by 3 from both sides;

3n = d - 2m

n = d - 2m

*Pretend there is a fraction bar between d - 2m and 3
