10=2/(1-r)

Solution for 10=2/(1-r) equation:

10=2/(1-r)

We move all terms to the left:

10-(2/(1-r))=0


Domain of the equation: (1-r))!=0

We move all terms containing r to the left, all other terms to the right

-r)!=-1

r!=-1/1

r!=-1

r∈R


We add all the numbers together, and all the variables

-(2/(-1r+1))+10=0

We multiply all the terms by the denominator


-(2+10*(-1r+1))=0


We calculate terms in parentheses: -(2+10*(-1r+1)), so:

2+10*(-1r+1)

10*(-1r+1)+2

We multiply parentheses

-10r+10+2

We add all the numbers together, and all the variables

-10r+12

Back to the equation:

-(-10r+12)


We get rid of parentheses

10r-12=0

We move all terms containing r to the left, all other terms to the right

10r=12

r=12/10

r=1+1/5
