3/3x+9=2/2x+6
We move all terms to the left:
3/3x+9-(2/2x+6)=0
Domain of the equation: 3x!=0
x!=0/3
x!=0
x∈R
Domain of the equation: 2x+6)!=0We get rid of parentheses
x∈R
3/3x-2/2x-6+9=0
We calculate fractions
6x/6x^2+(-6x)/6x^2-6+9=0
We add all the numbers together, and all the variables
6x/6x^2+(-6x)/6x^2+3=0
We multiply all the terms by the denominator
6x+(-6x)+3*6x^2=0
Wy multiply elements
18x^2+6x+(-6x)=0
We get rid of parentheses
18x^2+6x-6x=0
We add all the numbers together, and all the variables
18x^2=0
a = 18; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·18·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$x=\frac{-b}{2a}=\frac{0}{36}=0$
