## Answers ( )

Answer:see the explanation

The system has infinity solutions

Step-by-step explanation:we have

—-> equation A

isolate the variable x

—-> equation B

Solve by the substitution method.

substitute equation B in equation A

solve for y

The system has infinity solutions

That means The equation A and equation B are the same line

Verifywe have

—-> equation A

—-> equation B

Multiply by -2 both sides equation B

so

Equation A and equation B is the same line

The system has infinity solutions
