Estimate the solution to the system of equations.

You can use the interactive graph below to find the solution.

-3x + 3y = 9

2x - 7y = - 14

x = - 7/5 y=8/5

Step-by-step explanation:

1. choose a variable to eliminate (i chose 6)

2. multiply the first equation by 2 and the second equation by 3

3. now you have

-6x+6y=18

6x-21y=-42

and the x's can now cancel out when you add the equations together

4. after adding the equations, you get

-15y=-24

5. solve for y (y = 8/5)

6. now plug in 8/5 for the y in one of the original equations to solve for x. (i chose the first one)

7. - 3x+3 (8/5) = 9

-3x+24/5=9

-3x=21/5

x = - 7/5
