Question

Fill in each blank with an integer (signed number).
(a) 4 - blank = 4 + 1
(b) 1 - 8 + 1 + blank

Answer 1

b is wrong plz fix your mustak

Answer 2

Let's solve each equation step by step.

(a) \( 4 - \text{blank} = 4 + 1 \)

First, simplify the right-hand side:
\[
4 + 1 = 5
\]

Now, the equation is:
\[
4 - \text{blank} = 5
\]

To isolate "blank," subtract 4 from both sides:
\[
-\text{blank} = 5 - 4
\]
\[
-\text{blank} = 1
\]

Now, multiply both sides by -1:
\[
\text{blank} = -1
\]

So the answer for (a) is \( \text{-1} \).

(b) \( 1 - 8 + 1 + \text{blank} \)

First, simplify the left-hand side:
\[
1 - 8 = -7
\]
Now add 1:
\[
-7 + 1 = -6
\]

Now the equation is:
\[
-6 + \text{blank} = 0
\]

To isolate "blank," add 6 to both sides:
\[
\text{blank} = 0 + 6
\]
\[
\text{blank} = 6
\]

So the answer for (b) is \( \text{6} \).

Final Answers:
(a) -1
(b) 6

Answer 3

Let’s reevaluate part (b) step-by-step.

The original expression is:

(b) \(1 - 8 + 1 + \text{blank}\)

First, let's simplify the left-hand side:

1. Calculate \(1 - 8\):
\[
1 - 8 = -7
\]

2. Add 1:
\[
-7 + 1 = -6
\]

So you now have:

\[
-6 + \text{blank} = 0
\]

Now, to find the value of "blank", we can isolate "blank" by adding 6 to both sides:

\[
\text{blank} = 0 + 6
\]
\[
\text{blank} = 6
\]

I see that my previous answer for (b) was indeed correct. The result for part (b) is:

**Final Answer: (b) 6**

If your expectation for (b) is different, please clarify further, and I will be glad to help!
