Question

What term can you add to 5/6x-4 to make it equivalent to 1/2x-4?

Answer 1

X=-6 hope this helps

Answer 2

$\dfrac{1}{2}x- 4 - (\dfrac{5}{6} x - 4 )$

$= \dfrac{1}{2}x- 4 - \dfrac{5}{6} x + 4$

$= \dfrac{1}{2}x - \dfrac{5}{6} x$

$= \dfrac{3}{6}x - \dfrac{5}{6} x$

$= -\dfrac{2}{6}x$

$= -\dfrac{1}{3}x$

Answer : - 1/3 x 
------------------------------------------------------

To check:
$\dfrac{5}{6}x - 4 + (- \dfrac{1}{3}x ) = \dfrac{5}{6}x- \dfrac{1}{3}x-4= \dfrac{5}{6}x- \dfrac{2}{6}x-4 = \dfrac{3}{6}x-4 = \dfrac{1}{2}x-4$
