Fill in each blank with an integer (signed number).

(a) 4 - blank = 4 + 1
(b) 1 - 8 + 1 + blank

3 answers

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

b is wrong plz fix your mustak

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!
