Question

Rozwiąż rownania . :
a) 3/-z = 5/8
b)4-a/a = 5/3
c)3/y-2 = 2/y-3
d)5/3 =4/-x
e)b-3/5 = b/2
f) z+2/5 = z-1/4



POOOOOOMOOOOOOOOCY ! :D

Answer 1

a)-z=3*8/5

-z=21/5

-z=4,2

z=-4,2

 

b)a=3(4-a)/5

a=12-3a/5

4a=12/5

4a=2,4/4

a=0,6

 

c)3(y-3)=2(y-2)

3y-9=2y-4

y=5

 

d)-x=3*4/5

-x=12/5

-x=2,4

x=-2,4

 

e)b=2(b-3)/5

b=2b-6/5

-b=-6/5

-b=-1,2/(-1)

b=1,2

 

f)4(z+2)=5(z-1)

4z+8=5z-5

-z=-13/(-1)

z=13
