tiny-mole [99]

Answer:

You can use Gaussian Elimination.

Double both sides of the first equation and add the second equation.

6x + 4y = 8

5x - 4y = 3

---------------

11x = 11

x = 1

5 - 4y = 3

-4y = -2

y = 1/2

Solve the proportion below. 7/x=19

alexgriva [62]

Answer:

The value of x is approximately 0.3684.

Step-by-step explanation:

Given:

$\frac{7}x}=19$

We need to solve the proportion.

Solution:

Now we can see that;

In given equation one number is fraction and other number is whole number.

Now To make whole number into fraction we will divide by 1.

hence the whole number will be equal to;

$19=\frac{19}{1}$

Now the new equation will be;

$\frac{7}{x}=\frac{19}{1}$

Now by cross multiplication we get;

$7\times1=19\times x\\\\7=19x$

Now dividing both side by 19 we get;

$\frac{7}{19}=\frac{19x}{19}\\\\x\approx0.3684$

Hence the value of x is approximately 0.3684.
