What is the solution to the following system of equations?

{y-2y=4

{y=5x+1

(-1,-4) or x = - 1, y = - 4

Step-by-step explanation:

You can solve this system of equations by (in the first equation) by isolating the variable so that y = - 4. Now that you know this, you can enter this info into the second equation to isolate the x value, which would be - 1. You can see if this is correct by plugging the numbers back into the equation.
