(3x+9)+x/27)+90=180
We move all terms to the left:
(3x+9)+x/27)+90-(180)=0
We get rid of parentheses
3x+x/27)+90-180+9=0
We multiply all the terms by the denominator
3x*27)+90-180+9+x=0
Wy multiply elements
81x^2=0
a = 81; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·81·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
