Answer 1

Răspuns:

Explicație pas cu pas:

[(a+1/3)×3/47-1/2]:35/2+4/7=1

[(a+1/3)×3/47-1/2]:35/2 = 1 - 4/7 = 3/7

[(a+1/3)×3/47-1/2] = 3/7*35/2 = 15/2

(a+1/3)×3/47 = 15/2 + 1/2 = 16/2 = 8

a+1/3 = 8×47/3 = 376/3

a = 376/3 - 1/3 = 375/3 = 125

Answer 2

Răspuns:

a = 125

Explicație pas cu pas:

[(a+1/3) x 3/47 - 1/2] : 35/2 + 4/7 =1

[(a+1/3) x 3/47 - 1/2] : 35/2 = 1 - 4/7

[(a+1/3) x 3/47 - 1/2] : 35/2 = 3/7

(a+1/3) x 3/47 - 1/2 = (3/7) x 35/2

(a+1/3) x 3/47 - 1/2 = 15/2

(a+1/3) x 3/47 = 15/2 + 1/2

(a+1/3) x 3/47 = 8

a+1/3 =8 : 3/47

a+1/3 =8 x 47/3

a+1/3 = 376/3

a = 376/3 - 1/3

a = 375/3

a = 125
