Przekształć wzór dodając wskazane zmienne: a) a/a-t = b/b-t (a,b,t) b) (a+b)x=b+c (,b,c,x) c) mx+nx=p ( m,x,n) d) ax-bx=c (a,b,x) e) ax-=bx+ac (x,a,b,c ) DAJE NAJLEPSZĄ!!

a) a/a-t = b/b-t (a,b,t) a/a-t = b/b-t a(b-t) = b(a-t) ab-at=ab-bt -at=-bt -a=-b a=b b) (a+b)x=b+c (a,b,c,x) (a+b)x=b+c x=b+c /a+b (a+b)x=b+c a+b=b+c/x a = b+c/x –b (a+b)x=b+c c = (a+b)x –b c) mx+nx=p ( m,x,n) x(m+n)=p x = p/m+n x(m+n)=p (m+n)=p/x m=p/x -n x(m+n)=p m+n = p/x n = p/x -m d) ax-bx=c (a,b,x) x(a-b) = c x = c/a-b x(a-b) = c a-b = c/x a=c/x +b x(a-b) = c a-b = c/x -b = c/x - a b=a - c/x e) ax-=bx+ac (x,a,b,c ) ax – bx =ac x (a-b)=ac x= ac/a-b ax = bx + ac ax – ac = bx a (x-c) = bx a = bx/x-c ax = bx + ac ax – bx =ac x (a-b)=ac a-b = ac/x -b = ac/x – a b = a – ac/x ax = bx + ac ax – bx =ac ax – bx/a =c c = ax-bx/a
