Question

if x/3-x/4=5, then x= ??

Answer 1

Answer:

answer is 60

Step-by-step explanation:

x/3 - x/4 = 5

=>(4x-3x)/12= 5

=>x/12 = 5

=>x = 12*5

=>x = 60

Answer 2

$\huge\sf\color{red}\underline{Questíon}$

$\dfrac{x}{3}$-$\dfrac{x}{4}$ = 5

Find x.

$\huge\sf\color{navy}\underline{Solution}$

=> $\dfrac{x}{3}$-$\dfrac{x}{4}$ = 5

• Take LCM

• LCM of 3 and 4 is 20

=> $\dfrac{4x - 3x}{12}$ = 5 ( By cross multiplication )

=> 4x - 3x = 5 × 12

=> x = 60
