Question

500x+240y=8, 130x+240y= 43/10

Find x.

Answer 1

Answer: The answer for this question is x=0.01

Answer 2

Answer:

x = 1/100

Step-by-step explanation:

Given Equation ;

500x + 240y = 8. 1)

130x + 240y = 43/10. 2)

By Subtracting The Equations We Get :

500x + 240y = 8.

130x + 240y = 43/10

(-) (-) (-)

__________________

370x = 8 - 43/10

__________________

370x = 8 - 43/10

=> 370x = 80 - 43/10

=> 370x = 37/10

=> x = 37/10 × 370

=> x = 1/10 × 10

=> x = 1/100

Now,

Substitute x value in equation 1)

=> 500x + 240y = 8

=> 500(1/100) + 240y = 8

=> 5 + 240y = 8

=> 240y = 8 - 5

=> y = 3/240

=> y = 1/80

•°• x = 1/100 & y = 1/80
