Question

-5y=-5
7x+6y= 7
Is (5,1) a solution of the system?

Answer 1

Answer:

No, (5,1) is not a solution of the system. (1/7,-1) is the solution of the system.

Step-by-step explanation:

Step1:

-5y= -5

divide -5 on both sides

y= 1

Step 2:

7x+6(1)=7

7x+6=7

   -6  -6

7x = 1

divide 7 on both sides

x = 1/7
