Question

4.rezolvati ecuatiile:
a)8x-35=941
b)1259-3y=602
c)17+4a=1025
d)5(14+b)=170
e)27(n-27)=27
f)(21-z):21=0
g)44:(c=44)=1
h)3x+4x-2-5x=0

Answer 1

8x-35=941=8x=941+35=8x=976
1259-3y=602=3y=1259-602=3y=657

Answer 2

8x= 941+35
x= 976:8
x= 122

2. - 3y= 602-1259
-3y= - 657
y= 657:3
y= 219

3. 4a= 1025-17
4a= 1008
a= 1008:4
a= 252

4. 5b= 170-70
5b= 100
b= 100:5
b= 20

5. n-27 = 0
n= 27

6. 21-z= 0×21
-z=-21
z= 21

7. c-44= 1-44
c-44= - 43
c= 1

8. 2x=2
x=1
