Question

Solve the equation: (3)/(7)-(2)/(5)x=5

Answer 1

Answer:

x = - $\frac{80}{7}$

Step-by-step explanation:

Given

$\frac{3}{7}$ - $\frac{2}{5}$ 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 = $\frac{160}{-14}$ = - $\frac{80}{7}$
