.15=(100,000-x)/x

Solution for .15=(100,000-x)/x equation:

.15=(100.000-x)/x

We move all terms to the left:

.15-((100.000-x)/x)=0


Domain of the equation: x)!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

-((-1x+100)/x)+.15=0

We add all the numbers together, and all the variables

-((-1x+100)/x)+0.15=0

We multiply all the terms by the denominator


-((-1x+100)+(0.15)*x)=0


We calculate terms in parentheses: -((-1x+100)+(0.15)*x), so:

(-1x+100)+(0.15)*x

We multiply parentheses

(-1x+100)+0.15x

We get rid of parentheses

-1x+0.15x+100

We add all the numbers together, and all the variables

-0.85x+100
