In this problem, is X 13/21?

If X is 13/21 what is the answer to this problem?
-2/3 x 13/21 + 3/7

If X isnt 13/21, what is X?

Answer 1

Answer:

x = - $\frac{3}{28}$

Step-by-step explanation:

Given

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

Multiply through by 42 ( the LCM of 3, 7 and 2 ) to clear the fractions

- 28x + 18 = 21 ( subtract 18 from both sides )

- 28x = 3 ( divide both sides by - 28 )

x = - $\frac{3}{28}$
