Question

solve the following system using substitution
x + y =5
x + y= -3

a. (2,3)
b. (3,2)
c. infinitely many solutions
d. no solutions

Answer 1

Ok so i gt that u can use A and B for both equations. D would be the best answer because none of the other answers fit the equations. And C can'd fit it because u could't use every number to get -3

Answer 2

i think it's c.infinitely many solutions cause there are others solutions to get -3
