6x+4((13.6-4x)/6)=13.2
We move all terms to the left:
6x+4((13.6-4x)/6)-(13.2)=0
We add all the numbers together, and all the variables
6x+4((-4x+13.6)/6)-(13.2)=0
We add all the numbers together, and all the variables
6x+4((-4x+13.6)/6)-13.2=0
We multiply all the terms by the denominator
6x*6)+4((-4x+13.6)-(13.2)*6)=0
We add all the numbers together, and all the variables
6x*6)+4((-4x+13.6)=0
Wy multiply elements
36x^2=0
a = 36; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·36·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
