Bot GPT 3.5 To solve this system of equations, we can use the method of substitution or elimination.
Let's first solve the first equation for y:
y = 9x + 12
Now, substitute this value of y into the second equation:
2x + 4(9x + 12) = -28
2x + 36x + 48 = -28
38x + 48 = -28
38x = -76
x = -2
Now, substitute x = -2 back into the first equation to solve for y:
-9(-2) + y = 12
18 + y = 12
y = 12 - 18
y = -6
Therefore, the solution to the system of equations is x = -2 and y = -6.
