x+(18/100)*x=50000

Solution for x+(18/100)*x=50000 equation:

x+(18/100)*x=50000

We move all terms to the left:

x+(18/100)*x-(50000)=0


Domain of the equation: 100)*x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

x+(+18/100)*x-50000=0

We multiply parentheses

18x^2+x-50000=0

a = 18; b = 1; c = -50000;
Δ = b2-4ac
Δ = 12-4·18·(-50000)
Δ = 3600001
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-\sqrt{3600001}}{2*18}=\frac{-1-\sqrt{3600001}}{36}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{3600001}}{2*18}=\frac{-1+\sqrt{3600001}}{36}
