Answer:

Explanation:

2x + 2y = -4 ...(Equation 1)

3x + 8y = 9 ...(Equation 2)

We can use the method of substitution or elimination. Here, let's solve it using the method of substitution:

From Equation 1, we can solve for x:

2x = -4 - 2y

x = (-4 - 2y) / 2

x = -2 - y ...(Equation 3)

Now substitute the value of x from Equation 3 into Equation 2:

3(-2 - y) + 8y = 9

-6 - 3y + 8y = 9

5y = 9 + 6

5y = 15

y = 15 / 5

y = 3

Now substitute the value of y back into Equation 3 to find x:

x = -2 - y

x = -2 - 3

x = -5

Therefore, the solution to the system of equations is:

x = -5

y = 3
