Answer:
Explanation:
To solve the system of equations by elimination, we want to eliminate one of the variables by adding the two equations together. We can add the equations as follows:
4x + 4y = 4
(-x - 4y = -14)
3x = -10
Now we can solve for x:
3x = -10
x = -10/3
Substitute this value of x into either of the original equations to solve for y. We can use the first equation:
4x + 4y = 4
4(-10/3) + 4y = 4
-40/3 + 4y = 4
4y = 4 + 40/3
4y = 52/3
y = 13/3
Therefore, the solution to the system of equations is x = -10/3 and y = 13/3, or (-10/3, 13/3).
