Question

solve the following equation and cheak the result.
(i) x/3+5-x/6+x/4=0
(ii) 6x+1/3+1=7x-3/2​

Answer 1

$1) \frac{x}{3} + 5 - \frac{x}{6} + \frac{x}{4} = 0$

$\frac{4x - 2x + 3x}{12} = 5$

$\frac{5x}{12} = 5$

$x = \frac{5 \times 12}{5}$

$x = 12$

$2)6x + \frac{1}{3} + 1 = 7x - \frac{3}{2}$

$6x - 7x = - \frac{3}{2} - \frac{1}{3}$

$- x = \frac{ - 9 - 3}{6}$

$- x = \frac{ - 12}{6}$

$- x = - 2$

$x = 2$
