Question

solve ittttt..........!!!​

Answer 1

Answer:

$x = \frac{5}{13}$

Step-by-step explanation:

$\frac{0.3 + 0.7x}{x} = 0.85$

$0.3 + 0.7x = 0.85x$

$0.3 = 0.85x - 0.7x$

$0.3 = 0.78x$

$\frac{0.3}{0.78} = x$

$x = \frac{5}{13}$

Answer 2

Answer:

Hey mate!!

here's ur ans-

x = 2

Step-by-step explanation:

0.3+0.7x = x × 0.85

0.3+0.7x = 0.85x

0.3 = 0.85x - 0.7x

0.3 = 0.15x

x = 0.3 / 0.15

x = 2
