Question

a) x+1/3= 4/6
b) 2x-3/4=6/2
c) x+4/5=x+1/7
f) 2x-3/4=x+3/5
g) x-3/x+7=3/5
h) 2x-1/x+4=1/5

Answer 1

a) x+ 1/3 = 4/6
x = 4/6 - 1/3
x = 1/3
b)2x-3/4=6/2
2x = 6/2 + 3/4
2x = 15/4
x = 15/4 : 2
x = 15/8
c)x+4/5=x+1/7
x - x = 1/7 - 4/5
f)2x-3/4=x+3/5
2x - x = 3/5+3/4
x = 27/20

Answer 2

a) 1/3 se amplifica cu 2 si da x+2/6=4/6 de unde x=2/6
b)6/2 se amplifica cu 2 si da 2x-3/4=12/4 de unde 2x=12/4+3/4 de unde x=7,5/4
c)x+4/5se amplifica cu 7 si 1/7 se amplifica cu 5 de unde rezulta .ca 2x=28/35-5/35 de unde x =7,(6)/35
f)2x-3/4=x+3/5 de unde 3/4 se amplifica cu 5 si 3/5 se amplifica cu 4 de unde rezulta .ca 3x= 15/20 - 12/20 de unde x=1/20
