Question

solve x/3 + x/4 + x/5 =47/20



. Also verify your answer.​

Answer 1

Step-by-step explanation:

x/3 + x/4 + x/5 = 47/20

(20x + 15x + 12x) / 60 = 47/20

47x / 60 = 47/20

x = 47/20 × 60/47

x = 3

Now, Verification

Putting the value of x = 3,

• L.H.S = x/3 + x/4 + x/5

= 3/3 + 3/4 + 3/5

= (60+45+36) /60

= 141/60

= 47/60

• R.H.S = 47/60
• L.H.S = R.H.S

Hence (Proved).

Hope it might help you❤

Answer 2

ANSWER = 3

QUESTION

x/3 + x/4 + x/ 5 = 47 / 20

SOLUTION

==> x / 3 + x / 4 + x /5 = 47 / 20

==> [ ( 4x + 3x )/ 12] + x / 5 = 47 / 20

==> 7x / 12 + x / 5 = 47 / 20

==> 47 x / 60 = 47/ 20

==> x = 47 × 60 / 47 × 20

x = 60 / 20

= 3

PROOF

substituting values of x by 3

3/3 + 3/4 + 3 /5 = 7 /4 + 3 /5

= 35 + 12 / 20

= 47 / 20

= RHS
