Question

Find the intercepts of each equation:x + y = 82x + y = -3​

Answer 1

Answer:

$x = - 11$

$y = 19$

Step-by-step explanation:

$x + y = 8 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ...1 \\ 2x + y = -3 \: \: \: \: \: \: \: \: \: \: \: ...2$

from equation 1, we get

$x = 8 - y$

now put x = 8 - y in equation 2

$2(8 - y) + y= -3 \\ 16 - 2y + y = - 3 \\ - y = - 3 - 16 \\ - y = - 19 \\ y = 19$

now put y = 19 in equation 1

$x + 19= 8 \\ x = 8 - 19 \\ x = - 11$

thus, x = -11 and y = 19

Answer 2

X=-11
Y=19
If on a graph it would be {-2x-8[-20,20,-10,10]}
