a)228=4x+28
b)35=37-2x
c) 10=5x-20
d)1000=100x-2500
e)4x-15=69
f)14x=196
g)20 x-5=35 
va rog mult..

Answer 1

a) 4x = 228 -28
    4x = 200
     x = 200:4
    x= 50
b) 2x = 37 -35
   2x = 2
    x = 2:2
    x= 1
c) 5x = 20-10
    5x = 10
    x = 10:5
    x = 2
d) 100x = 2500-1000
    100x = 1500
    x = 1500:100
    x=15
e) 4x = 69+15
    4x = 84
    x = 84:4 
    x= 21
f) x= 196:14
   x = 14
g) 20x = 35-5
    20x = 30
    x = 30/20 simplificat 3/2
