Answer:
The solution to this system is (4, 1/6).
Step-by-step explanation:
Please separate these two equations for clarity. I like to write them in column format:
2.5y + 3x = 27
5x – 2.5y = 5
---------------------
8x = 32, and x = 4.
Subbing 4 for x in the second equation yields 5(4) - 2.5y = 5.
Then 20 - 2.5y = 5, or 15 = 2.5y. Solving for y, we get y = 1/6.
The solution to this system is thus (4, 1/6).
