Answer:
The solution is (-1/2, -2)
Step-by-step explanation:
Given 6f-4g=1,6f-6g=5, write these in columnar form:
6f-4g=1
6f-6g=5
Change all of the signs in the first equation:
-6f + 4g = -1
6f-6g=5
-------------------
-2g = 4, and so g = -2
Substituting -2 for g in either equation enables us to find f. Let's use the first equation: 6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3
Then f = -1/2 and g = -2. The solution is (-1/2, -2)
