Answer:

(15,-24) is the solution of system of equations.

Step-by-step explanation:

We have system of equations.

We  have to solve it by graphing.

x+y=-9         (eq 1)

2x+y=6         (eq 2)

In first equation,

y = -x-9

slope = -1  and y - intercept= -9

in second equation,

y=-2x+6

slope = -2 and y-intercept = 6

In graph,the intersecting point is the solution of system of equations.

The intersecting point is (15,-24).

We have attached the graph

Answer:

The solution of the given system of equations is 'x= 15 and y= -24'.

Step-by-step explanation:

We are given the inequalities,

x + y = -9

2x + y = 6

To find the solution graphically, we will draw the graphs of both the equation.

Then, the point at which the graphs intersect will be the required solution.

As we can see from the graphs plotted of the equations,

x + y = -9

2x + y = 6

That, they intersect at the point ( 15,-24 ).

Thus, the solution of the given system of equations is 'x= 15 and y= -24'.

Which equation is the result of adding these two equations -2x+4y=17
Katyanochek1 [597]

The right answer is Option C.

Step-by-step explanation:

Given equations are;

-2x+4y=17   Eqn 1

3x-10y= -3   Eqn 2

Adding Eqn 1 and Eqn 2;

(-2x+4y)+(3x-10y)=17+(-3)\\-2x+4y+3x-10y=17-3\\3x-2x-10y+4y=14\\x-6y=14

The right answer is Option C.
