Question

Dau coroana si 95 de puncte urgwnt !!! Va rog !!!

Answer 1

a) 4*x = 8
   x = 8:4
   x = 2
b) 4*x=2
   x = 2:4
   x = 1/2
c) 2/3*x = 4/9
   x = 4/6:2/3
   x = 4/9 x 3/2
   x = 2/3
d) 5/7 * x = 1
   x = 1:5/7
   x = 1*7/5
   x = 7/5
e) 7/5:x = 1
   x = 7/5:1
   x = 7/5
f) 1/4 : x = 3/4
  x = 1/4 : 3/4
  x = 1/4 x 4/3
  x = 1/3
g) 1/4 : x = 3
  x = 1/4:3
  x = 1/4 x 1/3
  x = 1/12

Answer 2

a) 4x = 8
   x = 8/4         x = 2
b) 4x=2
   x = 2/4        x = 1/2
c) 2x/3= 4/9
   18x = 12    x=12/18=6/9=2/3
d) 5x/7 = 1       5x=7
     x=7/5
e) 7/5 pe x = 1
   x = 7/5
f) 1/4 pe x = 3/4
  x = 1/4 : 3/4
  x = 1/4 x 4/3      x = 1/3
g) 1/4 pe x = 3
 3 x = 1/4
  x = 1/4 x 1/3        x = 1/12

Sper că te-am ajutat!
