Solution for (6x-1)/4=7/(4x-2) equation:


D( x )

4*x-2 = 0

4*x-2 = 0

4*x-2 = 0

4*x-2 = 0 // + 2

4*x = 2 // : 4

x = 2/4

x = 1/2

x in (-oo:1/2) U (1/2:+oo)

(6*x-1)/4 = 7/(4*x-2) // - 7/(4*x-2)

(6*x-1)/4-(7/(4*x-2)) = 0

(6*x-1)/4-7*(4*x-2)^-1 = 0

(6*x-1)/4-7/(4*x-2) = 0

((6*x-1)*(4*x-2))/(4*(4*x-2))+(-7*4)/(4*(4*x-2)) = 0

(6*x-1)*(4*x-2)-7*4 = 0

24*x^2-16*x-26 = 0

24*x^2-16*x-26 = 0

2*(12*x^2-8*x-13) = 0

12*x^2-8*x-13 = 0

DELTA = (-8)^2-(-13*4*12)

DELTA = 688

DELTA > 0

x = (688^(1/2)+8)/(2*12) or x = (8-688^(1/2))/(2*12)

x = (4*43^(1/2)+8)/24 or x = (8-4*43^(1/2))/24

2*(x-((8-4*43^(1/2))/24))*(x-((4*43^(1/2)+8)/24)) = 0

(2*(x-((8-4*43^(1/2))/24))*(x-((4*43^(1/2)+8)/24)))/(4*(4*x-2)) = 0

(2*(x-((8-4*43^(1/2))/24))*(x-((4*43^(1/2)+8)/24)))/(4*(4*x-2)) = 0 // * 4*(4*x-2)

2*(x-((8-4*43^(1/2))/24))*(x-((4*43^(1/2)+8)/24)) = 0

( 2 )

2 = 0

x belongs to the empty set

( x-((4*43^(1/2)+8)/24) )

x-((4*43^(1/2)+8)/24) = 0 // + (4*43^(1/2)+8)/24

x = (4*43^(1/2)+8)/24

( x-((8-4*43^(1/2))/24) )

x-((8-4*43^(1/2))/24) = 0 // + (8-4*43^(1/2))/24

x = (8-4*43^(1/2))/24

x in { (4*43^(1/2)+8)/24, (8-4*43^(1/2))/24 }
