Answer:
2n +14 = 30 I can use inverse operations and solve for n.
Step-by-step explanation:
twice means 2 so twice a number,n, means 2 times n thus 2n.
sum means add so, 2n + 14
is means equal so 2n + 14 = 30
If you solve it you will find n = 8
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solving for n</u>
- 4(0.5n) - 4(3) = n - 0.25(12) + 0.25(8n)
- 2n - 12 = n - 3 + 2n
- -12 = n - 3
- n = 3 - 12
- n = -9
