Question

Which is the solution to the equation below? 4n+5=25-3n

Answer 1

`n = (20)/(7)`

Explanation:

`4n + 5 = 25 - 3n\\4n + 3n = 25 - 5 \\7n = 20\\\\n = (20)/(7)`

Answer 2

n = 20/7

Explanation:

4n+5=25-3n

Add 3n to each side

4n+3n+5=25-3n+3n

7n +5 = 25

Subtract 5 from each side

7n+5-5=25-5

7n = 20

Divide by 7

7n/7 = 20/7

n = 20/7
