Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
