Question

Solve x/2+3x/4-5x/6=21​

Answer 1

FIND:

The value of 'x'

GIVEN,

$\frac{x}{2} + \frac{3x}{4} - \frac{5x}{6} = 21$

SOLUTION:

$= > \frac{x}{2} + \frac{3x}{4} - \frac{5x}{6} = 21 \\ = > \frac{6x}{12} + \frac{9x}{12} - \frac{10x}{12} = 21 \\ = > \frac{6x + 9x - 10x}{12} = 21 \\ = > 15x - 10x = 21 \times 12 \\ = > 5x = 252 \\ = > x = \frac{252}{5}$

Answer 2

$\bold \blue{answer}$

$\frac{x}{2} + \frac{3x}{4} - \frac{5x}{6} = 21$

$\frac{ (6x - 9x + 10x)}{12} = 21$

$\frac{7x}{12} = 21$

$x = 21 \times \frac{12}{7}$

$x = 3 × 12$

$x = 36$
