Answer:
(-6, 8); the missing value is -6
Step-by-step explanation:
First, you need to solve the given equation for x
1: 2x + 3y = 12 (Given)
2: 2x = -3y + 12 (Subtract 3y from both sides to isolate x)
3: x = -1.5y + 6 (Divide both sides by 2)
Now, you can solve for the missing x in the solution set (x, 8):
where x = -1.5y + 6 and y = 8,
x = -1.5(8) + 6
x = -12 + 6
x = -6
So, the missing value is -6
