Question

x/2+x/3-x/4=7 ; find the value of x

Answer 1

Answer:

x=12

Step-by-step explanation:

x/2 + x/3= 3x + 2x/6=5x /6

5x/6-x/4= 20x- 6x/24=14x/24

14x/24=7

14x=7×24

14x=168

x=168/14

×=84/7

x=12

Answer 2

Answer:

$\huge{\boxed{{\boxed{\underline{\sf{x=12}}}}}$

Step-by-step explanation:

$\huge{\boxed{\boxed{\underline{\sf{SOLUTION-}}}}}$

$= ) \frac{x}{2} + \frac{x}{3} - \frac{x}{4} = 7 \\ taking \: lcm \: of \: 2, \: 3 \: and \: 4 = 12 \\ = ) \frac{6x + 4x - 3x}{12} = 7 \\ = )7x = 84 \\ = )x = \frac{84}{7} \\ = )x = 12$
