3 + 3b = 9

7 answers

b = 2
So
3 + 3(2) = 9

6 = 9

This statement is not true, so b does not equal 2. Let me recalculate:

3 + 3b = 9
3b = 6
b = 2

The correct answer is b = 2.
#2 - Solve for n. 5 + 2n = 9 n = * 1 point #
To solve for n in the equation 5 + 2n = 9, follow these steps:

1. Subtract 5 from both sides of the equation:
5 + 2n - 5 = 9 - 5
2n = 4

2. Divide both sides by 2 to isolate n:
2n / 2 = 4 / 2
n = 2

Therefore, n = 2.
#3 - Solve for f. 7 = 3f + 1 f = *
To solve for f in the equation 7 = 3f + 1, follow these steps:

1. Subtract 1 from both sides of the equation:
7 - 1 = 3f + 1 - 1
6 = 3f

2. Divide both sides by 3 to isolate f:
6 / 3 = 3f / 3
f = 2

Therefore, f = 2.
