180=1/2x+x

Solution for 180=1/2x+x equation:

180=1/2x+x

We move all terms to the left:

180-(1/2x+x)=0


Domain of the equation: 2x+x)!=0

x∈R


We add all the numbers together, and all the variables

-(+x+1/2x)+180=0

We get rid of parentheses

-x-1/2x+180=0

We multiply all the terms by the denominator


-x*2x+180*2x-1=0

Wy multiply elements

-2x^2+360x-1=0

a = -2; b = 360; c = -1;
Δ = b2-4ac
Δ = 3602-4·(-2)·(-1)
Δ = 129592
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:

$\sqrt{\Delta}=\sqrt{129592}=\sqrt{4*32398}=\sqrt{4}*\sqrt{32398}=2\sqrt{32398}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(360)-2\sqrt{32398}}{2*-2}=\frac{-360-2\sqrt{32398}}{-4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(360)+2\sqrt{32398}}{2*-2}=\frac{-360+2\sqrt{32398}}{-4}
