Solution for 1/2x+3x=170 equation:

1/2x+3x=170

We move all terms to the left:

1/2x+3x-(170)=0


Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R


We add all the numbers together, and all the variables

3x+1/2x-170=0

We multiply all the terms by the denominator


3x*2x-170*2x+1=0

Wy multiply elements

6x^2-340x+1=0

a = 6; b = -340; c = +1;
Δ = b2-4ac
Δ = -3402-4·6·1
Δ = 115576
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:

$\sqrt{\Delta}=\sqrt{115576}=\sqrt{4*28894}=\sqrt{4}*\sqrt{28894}=2\sqrt{28894}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-340)-2\sqrt{28894}}{2*6}=\frac{340-2\sqrt{28894}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-340)+2\sqrt{28894}}{2*6}=\frac{340+2\sqrt{28894}}{12}
