Question

in simultaneous equation x-y=10 and x-y=6 then x=. yx. ​

Answer 1

Answer:

Step-by-step explanation:

{x + y = 10 | (equation 1)

x - y = 6 | (equation 2)

Subtract equation 1 from equation 2:

{x + y = 10 | (equation 1)

0 x - 2 y = -4 | (equation 2)

Divide equation 2 by -2:

{x + y = 10 | (equation 1)

0 x+y = 2 | (equation 2)

Subtract equation 2 from equation 1:

{x+0 y = 8 | (equation 1)

0 x+y = 2 | (equation 2)

Collect results:

Answer: {x = 8, y = 2
