Use the linear combination method to solve.

{x+2y=1 x−2y=5

Step-by-step explanation:

1) x+27=1

 -27  -27

x = -26

2) x-2y=5 (solving for x)

     +2y  +2y

x = 5 + 2y

2) x-2y=5 (solving for y)

  -x       -x

2y = 5 -x

2y/2    5/2   -x/2

y = 5 - x

        2         (5-x over 2)  

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2
