Y=-x+4

y = 3x

solving systems using substitution

Okay so first you "substitute" 3x for y in the other equation so it looks like this 3x=-x+4 ... Then you solve for x by adding x to the other side so it's 4x = 4 then you divide by 4 and get x = 1 ... Then you have to find y so you pull x into one equation like this y = 3*1 so y=3 So the final answer is (1,3)

The answer is one becuase if you add - x tot he 3x you get 4 and then divide by four and get one
