Answer:
(x, y) = (5, 6)
Step-by-step explanation:
When you have two equations in "y = ..." form, you can equate the two expressions for y.
y = 2x -4
y = x +1 . . . . . both are given
__
Equating y to itself, we have ...
y = y
2x -4 = x +1 . . . . . substitute the given expressions
x = 5 . . . . . . . . . . add 4-x to both sides
Then either equation can be used to find y:
y = x +1 = 5 +1 = 6
The solution is (x, y) = (5, 6).
