Answer:
x could be 10
y could be 5
those are some possible answers.
{-4x+7y+5=-5
{0x-3y=-5 Solve the equation.
{-4x+7y+5=-5
{y=5/3 Substitute the value of y.
-4x+7(5/3)+5=-5 Plug in and solve.
x=65/12 You should get this answer.
Therefore: (x,y) = (65/12,5/3)
Here: 6y = 6x + 12
6y - 6x = 12
Divide by 6,
y - x = 2
Which is nothing but first equation!
In short, Your Answer would be: "Infinitely Many solutions"
