Solve the system of equation by graphing.

Question

x+y=8

7x+7y=56

 

Determine the solution of the system of equations. Select the correct choice below

 

A). The solution is ___. (Type an ordered pair.)

B). The infinitely many solutions.

C). There is no solutions.

Answer 1

7x + 7y = 56

7 (x + y) = 56

(x + y) = 56 / 7

x + y = 8

 

Due to the fact that either variable can be replaced by a positive value or a negative value, the answer will be B.
