The solution to a system of linear equations is (-3,-3). Which system of linear equations has this point as its solution?
x-5y = -12 and 3x+2y = -15
OX-5y=-12 and 3x+2y = 15
x-5y = 12 and 3x+2y = - 15
X-5y = 12 and 3x + 2y = 15​

Answer :

Answer:

Option c) is correct.

That is x-5y=12 and 3x+2y=-15 are the system of linear equations satisfies the point (-3,3) so this is the  solution.

Step-by-step explanation:

To verify that which system of linear equations having the solution (-3,-3)

Let  [tex]x-5y=12\hfill (1)[/tex]

and [tex]3x+2y=-15\hfill (2)[/tex]

To solve it we have to use elimination method

First multiply the equation(1) into 3 we get

[tex]3x-15y=36\hfill (3)[/tex]

Now subtracting the equations (2)and (3) the signs may vary in the second equation we get

[tex]3x-15y=36[/tex]

[tex]-3x-2y=+15[/tex]

________________

[tex]-17y=51[/tex]

_______________

[tex]y=-\frac{51}{17}[/tex]

[tex]y=-3[/tex]

Now substitue the value y=-3 in equation (1) we get

[tex]x-5y=12[/tex]

[tex]x-5(-3)=12[/tex]

[tex]x=12-15[/tex]

Therefore x=-3

Therefore the solution is (-3,-3)

Therefore Option c) is correct.

That is x-5y=12 and 3x+2y=-15 are the system of linear equations satisfies the point (-3,3) so  the solution is (-3,-3).
