Answer:
-9 1/2 -1 1/2
Step-by-step explanation:
Combine like terms
-1 3/4 y+ 1/4y = -1 1/2y
Combine Numbers
1 1/2 +2= 2.5
2.5-12 = -9 1/2
The missing number is 20
<h3>How to determine the number</h3>
We can see that the values at the top must be made equal to that at the bottom
For the top, we have
30 + 11 = 41
For the bottom, we should have:
21 + x = 41
Now, let's solve for 'x' to determine the missing figure;
21 + x = 41
collect like terms
x = 41 - 21
x = 20
Thus, the missing number is 20
