The linear combination method is applied to a system of equations as shown.4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
What is the solution of the system of equations?

(1,2)
(3,9)
(5,5)
(9,3)

Answers

2x = 18
x = 18/2
x = 9

4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3

- 2y = 3 - x
- 2y = 3 - 9
- 2y = - 6
y = - 6/ - 2
y = 3

==> (W=7) or (W=-22/4 to exclude <0)
If W=7 then  2*W-3=14-3=11
Area=7*11=77
