4/3*x-x=-1

Solution for 4/3*x-x=-1 equation:

4/3x-x=-1

We move all terms to the left:

4/3x-x-(-1)=0


Domain of the equation: 3x!=0

x!=0/3

x!=0

x∈R


We add all the numbers together, and all the variables

-1x+4/3x+1=0

We multiply all the terms by the denominator


-1x*3x+1*3x+4=0

Wy multiply elements

a = -3; b = 3; c = +4;
Δ = b2-4ac
Δ = 32-4·(-3)·4
Δ = 57
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{-(3)-\sqrt{57}}{2*-3}=\frac{-3-\sqrt{57}}{-6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{57}}{2*-3}=\frac{-3+\sqrt{57}}{-6}
