Question

8/29·[1/6(x+3)+1/8]=1/5

Answer 1

1/6(x+3)+1/8=1/5×29/8
1/6(x+3)+1/8=29/40
1/6(x+3)=29/40-1/8 amplificãm pe 1/8 cu 5
1/6(x+3)=29/40-5/40
1/6(x+3)=3/5
x+3=3/5×6
x+3=18/5
x=18/5-3 amplificãm pe 3 cu 5
x=18/5-15/5
x=3/5

Answer 2

8/29·[1/6(x+3)+1/8]=1/5 

Inmultesti ambele parti ale ecuatiei cu  29/8

= 1/6 × ( x + 3 ) + 1/8 = 29/40 

= 1/6x + 1/2 + 1/8 = 29/40 

Aduni fractiile 

1/6x + 5/8 = 29/40

Inmulteste ambele parti ale ecuatiei cu 120

20x + 75 = 87

20x = 87 - 75

20x = 12

x = 12/20  care se simplifica prim 4 ⇒ x = 3/5
