Answer 1

Answer:

(6x+4x-3x)/12=7

7x=84

x=84/7

x=12

✌️✌️

Answer 2

$\dfrac{x}{2}$ + $\dfrac{x}{3}$ - $\dfrac{x}{4}$ = 7

___________ [ GIVEN ]

• We have to find the value of x.

___________________________

→ $\dfrac{x}{2}$ + $\dfrac{x}{3}$ - $\dfrac{x}{4}$ = 7

Now.. take LCM of 2, 3, 4 i.e. 12

→ $\dfrac{6x\:+\:4x\:-\:3x}{12}$ = 7

→ 10x - 3x = 7(12)

→ 7x = 84

→ x = 12

_________ [ ANSWER ]

✡ VERIFICATION :

From above calculations we have x = 12

Put value of x in this equation : $\dfrac{6x\:+\:4x\:-\:3x}{12}$ = 7

=> $\dfrac{7(12)}{12}$ = 7

=> $\dfrac{84}{12}$ = 7

=> 7 = 7
