First set up the equation to find answer: y=7-x. Then add it to the variable. 3x-1(7-x)=1. So that makes it 3x+-7+-1=1. Add like terms -7+-1=-8, so 3x+-8=1. Now to find x just switch the 8 to the other side. So you end up with 3x=9 since when you take away a number from one side you need to use the opposite value so adding 8 to -8 will cancel it out, then add it to the other, then just divide. 9/3=3, from here just substitute to find y. y=7+3. y=10. The answer is x=2 and y=5. I hope I helped!

3x - y = 1
-3x -3x
-y = -3x + 1
__ ______
-1 -1
y = 3x -1
(then you plug it into the other equation)
x + 3x -1 = 7
4x -1 = 7
+1 +1
4x = 8
__ ___
4 4
x = 2
(then you go back and plug in x in the other equation we made earlier)
y = 3(2) -1
y = 6-1
y = 5
(so then your answers would be x=2 and y=5)
(and if you need it in point form then the answer would be (2,5))
