(-1/2)x-6+8x+7-x=0

Solution for (-1/2)x-6+8x+7-x=0 equation:

(-1/2)x-6+8x+7-x=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

7x+(-1/2)x+1=0

We multiply parentheses

-1x^2+7x+1=0

a = -1; b = 7; c = +1;
Δ = b2-4ac
Δ = 72-4·(-1)·1
Δ = 53
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{-(7)-\sqrt{53}}{2*-1}=\frac{-7-\sqrt{53}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{53}}{2*-1}=\frac{-7+\sqrt{53}}{-2}
