x+(1/2)x=850

Solution for x+(1/2)x=850 equation:

x+(1/2)x=850

We move all terms to the left:

x+(1/2)x-(850)=0


Domain of the equation: 2)x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

x+(+1/2)x-850=0

We multiply parentheses

x^2+x-850=0

a = 1; b = 1; c = -850;
Δ = b2-4ac
Δ = 12-4·1·(-850)
Δ = 3401
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-\sqrt{3401}}{2*1}=\frac{-1-\sqrt{3401}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{3401}}{2*1}=\frac{-1+\sqrt{3401}}{2}
