Answer:
The solution is (3, 1)
Step-by-step explanation:
Use the method "elimination by addition and subtraction." Multiply all terms of the first equation by -3, obtaining
-3x - 6y = -15
and combine this result with the second equation:
-3x - 6y = -15
3x + 5y = 14
-----------------------
-y = -1, or y = 1.
Substituting this result, y = 1, into the first equation yields
x + 2(1) = 5, or x + 2 = 5, or x = 3.
The solution is (3, 1)
