Question

For the equations with variables x and y, if Dx = 26, Dy = −39 and D =
13 then x =?

Answer 1

Answer:

DX = 26

Dy = -39

D = 13

x = ?

D = 13 so x = ?

D = 13 so y = -39

D - (-y)

13 - (-39)

y = -26

D = 26

D

x = 13

D + x

13 + 13 = 26

Answer 2

The value of x = 2

Given :

For the equations with variables x and y$\sf{D_x = 26 \: , \: D_y = - 39 \: , \: D = 13}$

To find :

The value of x

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that for the equations with variables x and y$\sf{D_x = 26 \: , \: D_y = - 39 \: , \: D = 13}$

Step 2 of 2 :

Find the value of x

$\displaystyle \sf{x = \frac{D_x}{D} = \frac{26}{13} = 2 }$

$\displaystyle \sf{y = \frac{D_y}{D} = \frac{ - 39}{13} = - 3 }$

Hence the required value of x = 2
