Answer: -6 5/12 or -6.42
Step-by-step explanation:
From the question, 5 -12 - + 5/4 = 2/3
Let the missing value be x
Then subtract 5 from 12
-7 - x + 5/4 = 2/3
Add 7 to both sides
= -7 - x + 5/4 +7 = 2/3 +7
+7 cancels -7 on the left hand side of the equation
= -x + 5/4 = 2/3 +7
Then, subtract 5/4 from both sides to get
-x = 2/3 - 5/4 +7
-x= 77/12
x = -6 5/12 or -6.42
I hope this helps
