Solve the system by elimination

x+3y=5

-x-y=-3

y = 4

               x = -7

Step-by-step explanation:

1.) x + 3y = 5

       -x -y=3

2.) x + 3y = 5

        - 3y  - 3y

3.) x= 5-3y

4.) -(5-3y)-y=3

5.) -5+3y-y=3

6.) 2y-5=3

7.) 2y-5=3

         +5 +5

8.) 2y=8

9.) 2y/2 = 8/2

10.) y= 8/2

11.) y=4

12.) x+3 (4)=5

13.) x+12=5

14.) x+12=5

       -12  -12

15.) x= -7

answer.) y= 4

              x= -7

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
