Question

2x+3y=10 4x-5y =2 find x and y​

Answer 1

Answer:

x=40/11

y=10/11

Step-by-step explanation:

2x+3y=10.............(1)

4x-5y=2................(2)

subtract (1) and (2)

(2x+3y)-(4x-5y)=10-2

2x+3y-4x+5y=8

8y-2x=8

2(4y-x)=8

4y-x=4

4(y-x/4)=4

y-x/4=1

Y=x/4

now put in equation (1)

2x+3y=10

2x+3x/4=10

(8x+3x)/4=10

11x/4=10

x=(10×4)/11

x=(10×4)/11x=40/11

x=(10×4)/11x=40/11y=x/4

x=(10×4)/11x=40/11y=x/4 = 10/11
