5x/2x-3=3/7x+4
We move all terms to the left:
5x/2x-3-(3/7x+4)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 7x+4)!=0We get rid of parentheses
x∈R
5x/2x-3/7x-4-3=0
We calculate fractions
35x^2/14x^2+(-6x)/14x^2-4-3=0
We add all the numbers together, and all the variables
35x^2/14x^2+(-6x)/14x^2-7=0
We multiply all the terms by the denominator
35x^2+(-6x)-7*14x^2=0
Wy multiply elements
35x^2-98x^2+(-6x)=0
We get rid of parentheses
35x^2-98x^2-6x=0
We add all the numbers together, and all the variables
-63x^2-6x=0
a = -63; b = -6; c = 0;
Δ = b2-4ac
Δ = -62-4·(-63)·0
Δ = 36
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{36}=6$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-6)-6}{2*-63}=\frac{0}{-126} =0 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-6)+6}{2*-63}=\frac{12}{-126} =-2/21 $
