Solution for 5x+14/2x=13 equation:

5x+14/2x=13

We move all terms to the left:

5x+14/2x-(13)=0


Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R


We multiply all the terms by the denominator


5x*2x-13*2x+14=0

Wy multiply elements

10x^2-26x+14=0

a = 10; b = -26; c = +14;
Δ = b2-4ac
Δ = -262-4·10·14
Δ = 116
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{116}=\sqrt{4*29}=\sqrt{4}*\sqrt{29}=2\sqrt{29}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-26)-2\sqrt{29}}{2*10}=\frac{26-2\sqrt{29}}{20}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-26)+2\sqrt{29}}{2*10}=\frac{26+2\sqrt{29}}{20}
