Answer:
C) 4/15
Step-by-step explanation:
The two equations ...
- 2x + 1/2y = 2
- 1/2x + 2y = 6
can be solved for x using Cramer's rule:
x = (2·2 -1/2·6)/(2·2 -1/2·1/2) = (4-3)/(4-1/4) = 1/(15/4)
x = 4/15
_____
Cramer's rule for the solution to ...
is ...
- ∆ = ae-db
- x = (ce -fb)/∆
- y = (fa-dc)/∆
