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!!

Answer 1

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
