Question

Va rog ajutati-ma la exercițiul 4 , dau coroana

Answer 1

a) 8x= 941+35

8x =976

x =976:8

x =122

b) 3y=1259-602

3y = 657

y = 657:3

y = 219

c) 4a=1025-17

4a = 1008

a = 1008:4

a = 252

d) 14+b=170:5

14+b= 34

b = 34-14

b = 20

e) n- 27=27:27

n- 27 = 1

n = 27+1

n = 28

f) 21-z =0×21

21-z = 0

z= 21+0

z = 21

g) c +44 =1×44

c +44=44

c= 44-44

c = 0

h) 7x-5x-2=0

2x-2=0

2x = 2+0

2x =2

x = 2:2

x = 1
