Question

Solve the system by graphing. Then classify the system.?
6x-y=50
6x+7y=-14
What is the solution of the system?
(type an ordered pair. Type N if there is no solution. Type R if the solution is all real numbers)

Answer 1

Subtract the second equation from the first and get
-8y = 64
y = -8
Now use the first equation and the y answer
6x +8 = 50
6x = 42
x = 7
(7, -8)
