Step-by-step explanation:
Expand the following:
(2 x + k y = 3, x (k + 5) + 25 y = 2 k + 5)
x (k + 5) = x k + x 5:
(2 x + k y = 3, x k + 5 x + 25 y = 2 k + 5)
Subtract 3 from both sides of 2 x + k y = 3:
(2 x + k y - 3 = 3 - 3, 5 x + x k + 25 y = 2 k + 5)
3 - 3 = 0:
(2 x + k y - 3 = 0, 5 x + x k + 25 y = 2 k + 5)
Subtract 2 k + 5 from both sides of x×5 + x k + 25 y = 2 k + 5:
(2 x + k y - 3 = 0, 5 x + x k + 25 y - 2 k + 5 = (2 k + 5) - 2 k + 5)
(2 k + 5) - (2 k + 5) = 0:
(2 x + k y - 3 = 0, 5 x + x k + 25 y - (2 k + 5) = 0)
-(2 k + 5) = -5 - 2 k:
Answer: |
| (2 x + k y - 3 = 0, 5 x + x k + 25 y + -5 - 2 k = 0)
