x in (-oo:+oo)
5-((2/5)*(x+24)) = (-3/4)*(x+15) // - (-3/4)*(x+15)
5-((2/5)*(x+24))-((-3/4)*(x+15)) = 0
(-2/5)*(x+24)+(3/4)*(x+15)+5 = 0
3/4*(x+15)-2/5*(x+24)+5 = 0
3/4*(x+15)-2/5*(x+24)+5 = 0
7/20*x+33/20+5 = 0
7/20*x+133/20 = 0
7/20*x+133/20 = 0
7/20*x+133/20 = 0 // - 133/20
7/20*x = -133/20 // : 7/20
x = -133/20/7/20
x = -19
x = -19
