a-5=(2a+4/9)
We move all terms to the left:
a-5-((2a+4/9))=0
We add all the numbers together, and all the variables
a-((+2a+4/9))-5=0
We multiply all the terms by the denominator
a*9))-((+2a+4-5*9))=0
We add all the numbers together, and all the variables
a*9))-((2a-41))=0
We add all the numbers together, and all the variables
a*9))-((2a=0
Wy multiply elements
9a^2=0
a = 9; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·9·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
