Find a solution to the following system of equations. -2x + y= -3 -x+2y+3

For this case we have the following system of equations:

We multiply the first equation by -2:

We add the equations:

Adding we have:

We look for the value of "y":

So, the solution is

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
