(n+8)+3=(n+8)+3)/2
We move all terms to the left:
(n+8)+3-((n+8)+3)/2)=0
We get rid of parentheses
n-((n+8)+3)/2)+3+8=0
We multiply all the terms by the denominator
n*2)+3+8-((n+8)+3)=0
We add all the numbers together, and all the variables
n*2)+3+8-((n+8)=0
Wy multiply elements
2n^2=0
a = 2; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·2·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$n=\frac{-b}{2a}=\frac{0}{4}=0$
