X-(13-(1/3X))=0
Domain of the equation: 3X))!=0We add all the numbers together, and all the variables
X!=0/1
X!=0
X∈R
X-(13-(+1/3X))=0
We multiply all the terms by the denominator
X*3X))-(13-(+1=0
Wy multiply elements
3X^2+1=0
a = 3; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·3·1
Δ = -12
Delta is less than zero, so there is no solution for the equation
