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
