Use algebraic rules of equations to predict the solution type to the system of equations. Include all of your work for full credit. x + 2y = 10 6y = -3x + 30

Respuesta :

Answer: infinitely many solutions

Step-by-step explanation: 6y = -3x + 30 rewrites to 3x + 6y = 30

1. align equations x + 2y = 10

                           3x + 6y = 30

2. multiply first equation by -3 to get -3x - 6y = -30

3. align equations -3x - 6y = -30

                               3x + 6y = 30

4. add the equations and you they cancel out, which means infinitely many solutions
