Answer:

x = - [tex]\frac{80}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{7}[/tex] - [tex]\frac{2}{5}[/tex] x = 5

Multiply through by 35 ( the lcm of 7 and 5 ) to clear the fractions

15 - 14x = 175 ( subtract 15 from both sides )

- 14x = 160 ( divide both sides by - 14 )

x = [tex]\frac{160}{-14}[/tex] = - [tex]\frac{80}{7}[/tex]
