Question

Two lines, A and B, are represented by the following equations:

Line A: 2x + y = 6
Line B: x + y = 4

Which statement is true about the solution to the set of equations?
It is (2, 2).
There are infinitely many solutions.
It is (4, 0).
There is no solution.

Answer 1

Line A:
2x+y=6
Line B:
x+y=4
2x+2y=8

2x+2y=8
-
2x+y=6
=
y=2
x=2. As a result, It is (2, 2) is the final answer. Hope it help!
