Question

x/2 + x/3 - x/4 =7
it's urgent​

Answer 1

Step-by-step explanation:

Hello...

Here is your answer...

We have,

\frac{x}{2} + \frac{x}{3} - \frac{x}{4} = 7

2

x

+

3

x

−

4

x

=7

LCM of denominators 2,3,4 on LHS is 12. Multiplying both sides by 12 , we get

\begin{gathered}6 x + 4x - 3x = 7 \times 12 \\ \\ = > 7x = 7 \times 12 \\ \\ = > 7x = 84 \\ \\ = > \frac{7x}{7} = \frac{84}{7} \\ \\ = > x = 12\end{gathered}

6x+4x−3x=7×12

=>7x=7×12

=>7x=84

=>

7

7x

=

7

84

=>x=12
