Answer:

x = -26 and y = 24.

Explanation:

Multiply the second equation by 3 to get rid of the y variable:

-6x + 3y = 12

Add the two equations together, eliminating the y variable:

4x + 6y = 40

-6x + 3y = 12

-2x = 52

Solve for x:

-2x = 52

x = -26

Substitute the value of x into one of the original equations to solve for y:

4x + 6y = 40

4(-26) + 6y = 40

-104 + 6y = 40

6y = 144

y = 24

Therefore, the solution to the system of equations is x = -26 and y = 24.
