Question

x/2+x/3+x/4=13 and verify if x=12​

Answer 1

Step-by-step explanation:

x/2+x/3+x/4=13

puting the value of x=12

12/2+12/3+12/4=13

6+4+3=13

13=13

so,x/2+x/3+x/4=13 #

Answer 2

Answer:

$\frac{x}{2} +\frac{x}{3}+\frac{x}{4} =13$

lcm=12

⇒$\frac{6x+4x+3x}{12}$=13

⇒$\frac{13x}{12} =13$

⇒13x=13×12

⇒x=$\frac{13*12}{13}$

⇒x=12

 Hence proved.
