Rezolvati  ecuatile: a) 4x=80

                               b) 180 : x =10

                               c) 14+2x = 20

Răspuns :

a) x=80:4
x=20
b)x=180:10
x=18
c)2x=20-14
2x=6
x=6:2
x=3
a) 4x = 80
x = 80 : 4 = 20

b) 180 : x = 10
x = 180 : 10 = 18 

c) 14 + 2x = 20
2x = 20 - 14
2x = 6
x = 6 : 2 = 3
