Question

5x-9y=1300
3x-5y=900

x=?
y=?​

Answer 1

Step-by-step explanation:

By Using elimination method :

We get x = 300

And y = 800

Answer 2

Answer:

see in explanation

Step-by-step explanation:

multiplying eqn 1 by 3 and 2 by 5

15x-27y=3900

15x-25y=2700(by subtracting)

-2y=1200

y=1200/-2

y=-600

putting value of y in eqn 2

3x-5y=900

3x-5(-600)=900

3x+3000

3x=900-3000

3x=-2100

X=-2100/3

X=-700

Hence,X=-700 and Y=-600
