Question

Solve for x and y: x by 2+y=0.8 and 7 by y =10​

Answer 1

Step-by-step explanation:

$\frac{x}{2 + y} = \frac{8}{10} and \: \frac{7}{y} = 10$

Here the value of y

$y = \frac{7}{10}$

So putting the value of y .

$\frac{x}{2 + \frac{7}{10} } = \frac{8}{10}$

$\frac{x \times 10}{20 + 7} = \frac{8}{10}$

$= \frac{10x}{27} = \frac{8}{10}$

$100x = 216$

$x = 0.216$

So the value of x= 0.216 and y= 0.7
