Final answer:

The system of linear equations 11x + 4y = -46 and 7x - 4y = 10 is solved using the elimination method, obtaining the solution x = -2 and y = -6.

Step-by-step explanation:

The student's question involves a system of linear equations, which can be solved using various methods such as substitution, elimination, or graphing. Here, the two given equations are:

  • 11x + 4y = -46
  • 7x - 4y = 10

To solve the system, we can use the elimination method, adding the two equations together to eliminate the y terms:

11x + 4y + 7x - 4y = -46 + 10

This simplifies to:

18x = -36

Dividing both sides by 18 gives us:

x = -2

Substituting x = -2 into one of the original equations to find the value of y:

11(-2) + 4y = -46

Which simplifies to:

-22 + 4y = -46

Adding 22 to both sides gives us:

4y = -24

Dividing by 4 we get:

y = -6

Thus, the solution to the system of equations is x = -2 and y = -6.
