Чему равен корень уравнения:
1) [tex] \frac{x-8}{x+2} [/tex]=[tex]\frac{7}{3} [/tex]
2) [tex] \frac{4}{x-1,2} [/tex]=[tex] \frac{15}{x-10} [/tex]

1) (х-8)/(х+2) =7/33(х-8) = 7(х+2)3х-24 = 7х+147х-3х = -24-144х = -38х = -38/4х = -19/2х = -9,52) 4/(х-1,2) = 15/(х-10)4(х-10) = 15(х-1,2)4х-40 = 15х-1815х-4х = -40+1811х = -22х = -22/11х = -2
