Answer:
n = 21
Step-by-step explanation:
5(n-7)=2(n+14)
Distribute
5n -35 = 2n+28
Subtract 2n from each side
5n-2n -35 = 2n-2n +28
3n-35 =28
Add 35 to each side
3n-35+35 = 28+35
3n = 63
Divide by 3
3n/3 = 63/3
n =21
Answer: 1 and 7/15
Step-by-step explanation:
I made the common donominator 15 and then did the problem but the donominator stays the same
Step 1: Add 3 to both sides.
2x-3+3=7+3
2x=10
Step 2: Divide both sides by 2.
2x/2=10/2
x=5

8m+7m+4n-2n
15m+2n
You know that 3 times 2 is 6 so 30'times 20 equals 60
