what is the solution to the system y= 2x-3 y= -x+3

Answers

You would have to step up your problem like this 2x-3=-x+3, then you add -x to both sides. So, the problem will look like this 3x-3=3 then add to both sides. The ending problem will look like this 3x=6 then divide 3 to both sides then your answer is 2! Hopefully this is correct!
