3/5x-7.2=-4x-35
We move all terms to the left:
3/5x-7.2-(-4x-35)=0
Domain of the equation: 5x!=0We get rid of parentheses
x!=0/5
x!=0
x∈R
3/5x+4x+35-7.2=0
We multiply all the terms by the denominator
4x*5x+35*5x-(7.2)*5x+3=0
We multiply parentheses
4x*5x+35*5x-36x+3=0
Wy multiply elements
20x^2+175x-36x+3=0
We add all the numbers together, and all the variables
20x^2+139x+3=0
a = 20; b = 139; c = +3;
Δ = b2-4ac
Δ = 1392-4·20·3
Δ = 19081
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(139)-\sqrt{19081}}{2*20}=\frac{-139-\sqrt{19081}}{40} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(139)+\sqrt{19081}}{2*20}=\frac{-139+\sqrt{19081}}{40} $
