1/2x=-7/9x+3
We move all terms to the left:
1/2x-(-7/9x+3)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 9x+3)!=0We get rid of parentheses
x∈R
1/2x+7/9x-3=0
We calculate fractions
9x/18x^2+14x/18x^2-3=0
We multiply all the terms by the denominator
9x+14x-3*18x^2=0
We add all the numbers together, and all the variables
23x-3*18x^2=0
Wy multiply elements
-54x^2+23x=0
a = -54; b = 23; c = 0;
Δ = b2-4ac
Δ = 232-4·(-54)·0
Δ = 529
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{529}=23$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(23)-23}{2*-54}=\frac{-46}{-108} =23/54 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(23)+23}{2*-54}=\frac{0}{-108} =0 $
