x=20+(1/2)x
We move all terms to the left:
x-(20+(1/2)x)=0
Domain of the equation: 2)x)!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
x-(20+(+1/2)x)=0
We multiply all the terms by the denominator
x*2)x)-(20+(+1=0
Wy multiply elements
2x^2+1=0
a = 2; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·2·1
Δ = -8
Delta is less than zero, so there is no solution for the equation
