147/x=3x

We move all terms to the left:

147/x-(3x)=0

Domain of the equation: x!=0We add all the numbers together, and all the variables

x∈R

-3x+147/x=0

We multiply all the terms by the denominator

-3x*x+147=0

Wy multiply elements

-3x^2+147=0

a = -3; b = 0; c = +147;

Δ = b^{2}-4ac

Δ = 0^{2}-4·(-3)·147

Δ = 1764

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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1764}=42$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-42}{2*-3}=\frac{-42}{-6} =+7 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+42}{2*-3}=\frac{42}{-6} =-7 $
