Question

-3x + 3y =3 -5x + y =13 Solve as a whole number

Answer 1

Answer:

x = -3, y = -2

(-3, -2)

Step-by-step explanation:

-3x + 3y = 3

-5x + y = 13

-5x + y = 13

+5x    +5x

y = 5x + 13

-3x + 3(5x + 13) = 3

-3x + 15x + 39 = 3

12x + 39 = 3

     - 39   -39

12x = -36

/12    /12

x = -3

Now, we solve for y:

-5x + y = 13

-5(-3) + y = 13

15 + y = 13

-15      -15

y = -2

(x, y) -> (-3, -2)

Hope this helps!
