What is the solution to this system of linear equations? y − x = 6 y + x = −10 a. (−2, −8) b. (−8, −2) c. (6, −10) d. (−10, 6)

ITS NOT C OR D>ITS A OR B <

B

Step-by-step explanation:

1.8 or

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
