Va rog dau coroana!!! ​

Answer 1

Răspuns:

R:6,2(7)

Explicație pas cu pas:

41+3×{36:9+3×[50+3×(a:8-98:2)]}=536

3×{4+3×[50+3×(a:8-49)]}=536-41

4+3[50+3(a:8-49)]=495:3

3[50+3(a:8-49)]=165-4

50+3(a:8-49)=161:3

3(a:8-49)=161:3-50

a:8-49=(161:3-50):3

a:8-49=[53,(6)-50]:3

a:8-49=3,(6):3

a:8-49=1,(2)

a:8=49+1,(2)

a:8=50,(2)=50 2/9=452/9

a=452/72=6,2(7)
