x+5=54/x

Solution for x+5=54/x equation:

x+5=54/x

We move all terms to the left:

x+5-(54/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

We get rid of parentheses

x-54/x+5=0

We multiply all the terms by the denominator


x*x+5*x-54=0

We add all the numbers together, and all the variables

5x+x*x-54=0

Wy multiply elements

x^2+5x-54=0

a = 1; b = 5; c = -54;
Δ = b2-4ac
Δ = 52-4·1·(-54)
Δ = 241
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{-(5)-\sqrt{241}}{2*1}=\frac{-5-\sqrt{241}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+\sqrt{241}}{2*1}=\frac{-5+\sqrt{241}}{2}
