Question

Pls I need the answer with steps​

Answer 1

x = - 3.75

y = 28.75

Explanation:

`\begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases}`

Since, x + y = 25

Therefore, y = 25 - x..... (1)

5x + y = 10......(2)

Plug y = 25 - x in equation (2), we find:

5x + 25 - x = 10

5x - x = 10 - 25

4x = - 15

x = - 15/4

x = - 3.75

Plug x = - 3.75 in equation (1), we find:

y = 25 - (- 3.75)

y = 25 + 3.75

y = 28.75

(x, y) = (-3.75, 28.75)

Answer 2

Point form of the equation:
(-15/4 , 115/4) on the graph

So
x = -15/4
y= 115/4

Hope it’s right
