Question

Find the value of x if the mean of -2/3, x, -4/3 is -11/14?

Answer 1

Answer:

$\frac{ - 5}{14}$

Step-by-step explanation:

$mean \: = \frac{sum \: \: of \: \: terms}{number \: \: of \: \: terms}$

$\frac{ \frac{ - 2}{3} + x - \frac{4}{3}}{3} = - \frac{11}{14}$

$\frac{ - 2 + 3x - 4}{9} = - \frac{11}{14}$

$\frac{3(x - 2)}{9} = - \frac{11}{14}$

$14(x - 2) = - 33$

$14x- 28 = - 33$

$14x = - 5$

$x = \frac{ - 5}{14}$
