7x-6x/9x=15
We move all terms to the left:
7x-6x/9x-(15)=0
Domain of the equation: 9x!=0We multiply all the terms by the denominator
x!=0/9
x!=0
x∈R
7x*9x-6x-15*9x=0
We add all the numbers together, and all the variables
-6x+7x*9x-15*9x=0
Wy multiply elements
63x^2-6x-135x=0
We add all the numbers together, and all the variables
63x^2-141x=0
a = 63; b = -141; c = 0;
Δ = b2-4ac
Δ = -1412-4·63·0
Δ = 19881
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{19881}=141$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-141)-141}{2*63}=\frac{0}{126} =0 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-141)+141}{2*63}=\frac{282}{126} =2+5/21 $
