Answer 1

Answer:

1. is n= -32

2. is n=-3.2

3. is n= -0.2

4. is n=-5

Step-by-step explanation:

For problem 1:

n/8+1/2=-3 1/2

Simplify both sides of the equation:

1/8 + 1/2 = -7/2

Subtract 1/2 from both sides:

1/8n + 1/2- 1/2 = -7/2-1/2

1/8n= -4

Multiply both sides by 8:

8*(1/8n) = 8* (-4)

Answer:

n=-32

For problem 2:

−1.4n+2.1=6.58

Step 1: Subtract 2.1 from both sides.

−1.4n+2.1−2.1=6.58−2.1

−1.4n=4.48

Step 2: Divide both sides by -1.4.

−1.4n −1.4 = 4.48 −1.4

n=−3.2

For problem 3:

5.7n+4.1=2.96

Step 1: Subtract 4.1 from both sides.

5.7n+4.1−4.1=2.96−4.1

5.7n=−1.14

Step 2: Divide both sides by 5.7.

5.7n /5.7 = −1.14 /5.7

n=−0.2

For problem 4:

4n−2  3 /4 = −22  3 /4
