Solution for -2=15/2k-1/4(10k-4) equation:


k in (-oo:+oo)

-2 = (15/2)*k-((1/4)*(10*k-4)) // - (15/2)*k-((1/4)*(10*k-4))

(1/4)*(10*k-4)-((15/2)*k)-2 = 0

(1/4)*(10*k-4)+(-15/2)*k-2 = 0

1/4*(10*k-4)+(-15*k)/2-2 = 0

(1/4*2*(10*k-4))/2+(-15*k)/2+(-2*2)/2 = 0

1/4*2*(10*k-4)-15*k-2*2 = 0

-10*k-4-2 = 0

-10*k-6 = 0

(-10*k-6)/2 = 0

(-10*k-6)/2 = 0 // * 2

-10*k-6 = 0

-10*k-6 = 0 // + 6

-10*k = 6 // : -10

k = 6/(-10)

k = -3/5

k = -3/5
