/x+6=3x+4

Solution for /x+6=3x+4 equation:

/x+6=3x+4

We move all terms to the left:

/x+6-(3x+4)=0


Domain of the equation: x!=0

x∈R


We get rid of parentheses

/x-3x-4+6=0

We multiply all the terms by the denominator


-3x*x-4*x+6*x+=0

We add all the numbers together, and all the variables

2x-3x*x=0

Wy multiply elements

-3x^2+2x=0

a = -3; b = 2; c = 0;
Δ = b2-4ac
Δ = 22-4·(-3)·0
Δ = 4
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4}=2$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2}{2*-3}=\frac{-4}{-6}
=2/3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2}{2*-3}=\frac{0}{-6}
=0
