Question

3/4y+7÷2/5y-4=5/4 solve the equation

Answer 1

this is just a example Solution for 7+2/5y=3/5y-4 equation:

y in (-oo:+oo)

(2/5)*y+7 = (3/5)*y-4 // - (3/5)*y-4

(2/5)*y-((3/5)*y)+4+7 = 0

(2/5)*y+(-3/5)*y+4+7 = 0

11-1/5*y = 0 // - 11

-1/5*y = -11 // : -1/5

y = -11/(-1/5)

y = 55

y = 55
