Final answer:

To solve the system of equations 4x + 8y = 4 and -7x + 9y = -53, we can use either the substitution method or the elimination method. Let's use the elimination method in this case. The solution to the system of equations is x = -23, y = 12.

Step-by-step explanation:

To solve the system of equations 4x + 8y = 4 and -7x + 9y = -53, we can use either the substitution method or the elimination method.

Let's use the elimination method in this case. We'll multiply the first equation by -7 and the second equation by 4 to eliminate the x term:

-28x - 56y = -28

-28x + 36y = -212

Adding the two equations together, we get:

-20y = -240

y = 12

Substituting this value of y back into the first equation, we can solve for x:

4x + 8(12) = 4

4x + 96 = 4

4x = -92

x = -23

Therefore, the solution to the system of equations is x = -23, y = 12.
