1. What is the value of b in the equation

b + 8 = 13?

A. 5****
B. 8
C. 13
D. 21

2. The steps below show the incomplete solution to find the value of x for the equation
7x − 3x − 4 = −1 + 21:

Step 1: 7x − 3x − 4 = −1 + 21
Step 2: 7x − 3x − 4 = 20
Step 3: 4x − 4 = 20

Which of these is most likely the next step?

A. 4x = 24
B. 4x = 16 *****
C.4x = 5
D.4x = 80

Please check my answers thanks!!

Both of your answers are right.

Thank you!!

You're welcome.

yes

1. To find the value of b in the equation b + 8 = 13, you need to isolate b by subtracting 8 from both sides of the equation. Let's go through the steps:

b + 8 = 13

Step 1: Subtract 8 from both sides:
b + 8 - 8 = 13 - 8
b = 5

Therefore, the value of b in the equation is 5. So your answer A. 5 is correct!

2. Let's go through the steps to find the value of x for the equation 7x − 3x − 4 = −1 + 21:

Step 1: 7x − 3x − 4 = −1 + 21
Step 2: 7x − 3x − 4 = 20
Step 3: 4x − 4 = 20

Now, to find the next step, you need to isolate the variable x by adding 4 to both sides. Let's continue:

Step 4: 4x - 4 + 4 = 20 + 4
4x = 24

Therefore, the next step is A. 4x = 24. So your answer A. 4x = 24 is correct!

Great job on both answers!
