Solve the system below using substitution.
Given { y = - x + 5 { y = x + 3 { answer bellow }
Answer: Substitute -x+5 for y in the second equation and then add -x ti both sides to make -2x+5=3 take away 5 from both sides making the equation -2x= -2 and then you divide -2 by -2 that makes x=1
Substitute 1 for x in the first equation making y= -1+5 and that equals to 4 so y=4
As you can see the answer is y=4

Answer : y=4
(To make sure it is correct you can also do it by yourself, if needed..)
Substitute 1 for x in the first equation making y= -1+5 and that equals to 4 so
y = 4 - answer
