Question

13x+2y=1

5x-2y=-19

Solve for x and y

Answer 1

x = 6.5 and y = -22.1

Explanation:

13x/13 + 2y = 1/13

2y = 13

2y/2 = 13

y = 6.5

5x -2(6.5) = -19

5x (6.5) = -17

5x = -110.5

5x/5 = -110.5/5

x = -22.1

Answer 2

Explanation:

13x+2y=1

+ 5x-2y=-19

-------------------

18x=18

x=1

5x1-2y=-19

5-2y=-19

-2y=-19-5

-2y=14

-y=7

y=-7

x=1

y=-7
