x-4=2(x+8)/5
We move all terms to the left:
x-4-(2(x+8)/5)=0
We multiply all the terms by the denominator
x*5)-(2(x+8)-4*5)=0
We add all the numbers together, and all the variables
x*5)-(2(x+8)=0
Wy multiply elements
5x^2=0
a = 5; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·5·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
